At present, the solar inverters seen in the market are divided into three types in the f-application: 1·Off-grid, that is, a stand-alone product that does not have a battery in parallel with the mains. 2. Qing (gfid__ieet), and the city of Lai Lin Sun Optoelectronics into the city. 3. Hybrid, which can be connected to the battery in parallel with the mains. Off-line type 11⁄4 inverter, also known as Stand-along, as shown in Figure 1, the solar battery pack is used to charge the battery, and then the AC drive is used to send current to the AC load. Such a device has a great influence on the service life of the battery when the battery is frequently charged/discharged. Now, the manufacturing cost of the battery is high, which is bound to increase the replacement cost; further, because the battery is a separate type of inverter. The important parts, which take up a lot of space, are not conducive to environmental protection. The implementation of the parallel solar inverter can be divided into two types. As shown in Fig. 2, the structure is decomposed into two parts: charging and providing load power (discharge). M384459 charges the battery by charging the Taihe power supply. After that, the branch will connect the battery to the direct AC drive to provide load power. Such a device is currently the mainstream in the market, and its structure is an independent extension, and the input end of the battery increases the supply source of the utility. However, the green energy and the commercial power are still stored in the battery at the same time, which only improves the storage quality of the battery, and does not greatly improve the control function of the direct AC inverter. Another embodiment of the parallel type solar power inverter, as shown in Fig. 3, is to switch from the direct current to the battery via the solar energy and the battery to the load. This type of device has a slight improvement in the control function of the AC AC drive, which increases the switching function of the abnormal signal, but the green energy can still be reduced by the battery as the energy storage device. Therefore, the above structure has the following shortcomings: 1. Charge and discharge of the battery frequently, in addition to the battery life loss, the space occupied by the battery and the replacement cost are very amazing, in addition to highlighting the battery application benefits and The cost of using two outside is also quite environmentally friendly. 2, from Tai · change charm Xiang for the tree, when the lack of sunshine and temperature changes often _ solar cell photovoltaic capacity; and the solar wheel will be due to bumps and other changes, so Wei touch load The energy; that is, the sharp-track domain and the end-capacity battery _ maximum turn, such use is very inconvenient and complicated. 3. When the battery's internal energy is saturated, it is no longer able to charge the battery. 5 A waste of energy is formed. 4 _ Γ 合 型 地 地 11, also known as the secret _ change _, such as the rate L is not 'to control the conversion of the exchange after the conversion, wave type and frequency with the city and then micro-supply . This county is based on the city's main source of supply, green payment as a secondary source. The main disadvantage of the port is that the power quality characteristics such as power, waveform and frequency of the solar inverter are highly susceptible to interference from external power distribution and equipment, so it is necessary to control the above parameters of the thief _ _ _ (4), Not only is the frequency required to be complicated, expensive, but also often difficult to jump in the actual operation, causing troubles and stricter so-called islanding effects. %曰/Because these products are designed and used in the function of the UPS's uninterruptible power system, it is too much, the economic benefits are not good, and most customers and the market react. Hope to improve, it prompted the creator to start the regenerative riding 'electric power to m research engine and concept 0. This is the case, the creative designer for the above defects and deficiencies, after long-term research, and with the theory, finally created a species A creative design that addresses these shortcomings and shortcomings. [New content] The main purpose of this creation is to provide a kind of green energy composite power conversion equipment M384459. The composite green energy (solar energy, wind energy, etc.) is used as the main energy source, and the power supply is provided at the same time. · Conduct online power regulation to reduce energy consumption to achieve energy savings. The purpose of this creation is to provide a green energy composite power conversion device, which uses a DC BUS module to utilize current distribution (C_n Sharing) and pulse width modulation (PWM) control techniques. The power output has no switching time difference problem, and can maintain the power output of the crucible without the matching problem of the power quality characteristics. The purpose of this creation is to provide a green energy composite power conversion device. The smart shunt technology can receive multiple input sources to achieve a diversified usage mode to save manufacturing costs. A further object of the present invention is to provide a green energy composite power conversion device that utilizes a ready-to-go supply mode without using energy storage equipment to reduce manufacturing costs and meet environmentally friendly requirements. In order to achieve the above purpose of the creation, the following technical solutions can be realized: the present invention provides a green energy composite power conversion device, and the operation principle of the power conversion device is based on green energy as a main source of supply. The energy provided by the green energy (solar, wind energy, fuel cell, etc.) equipment is converted into DC voltage by DC/DC conversion and sent to the DC bus module, and then via the DC/AC converter. The electric energy is converted into an alternating current and then supplied to an AC load. When the green energy is weakened, the other green energy or mains (ACD0V/110V) converts the electric energy into DC power through the AC/DC converter and takes M384459 * * · · Green energy supply to the DC bus module (Using smart shunt technology). The DC bus bar module utilizes current distribution and pulse width modulation (PWM) control, and the pulse width machine of the stomach is a digital digit of the microprocessor. The output is controlled by the analog circuit. Technology. Therefore, it is possible to - track and measure the parallel _ energy record between the energy output of the entire output energy distribution; the other side also _ green Wei total output to the hybrid city into the current ratio, so that the DC bus module can maintain stability Voltage. When the energy of the green energy is sufficient, the green energy can be used as the power supply source. When the supply capacity of the DC bus module to the green energy is insufficient, the power switch (PowerSwitch) will be automatically turned on. The utility power is sent from the energy of the ac/dc converter to the DC busbar module to make up for the insufficient power, so that the output of the supply maintains a fixed output. The power conversion unit is also equipped with an external AC auto-converter (ATS). If the power conversion device fails during operation, it can automatically switch the power supply of the direct-supply power supply. In the real ride, the creation of the green energy composite power conversion device has an expansion function, I multi-group negative · stipulations - group re-sewing the power to change the age system, the instrument control center official system 'easy to maintain, easy to manage, save component materials and The labor cost and the customer's visual needs can be further expanded due to the demand. Compared with the prior art, the green energy composite power conversion device of the present invention has the following advantages of low cost and grid-connected type, and does not need to be added to the power condition monitoring device, the cost of the M384459 is much more saved; 2. the system is easy to set up; 3, solar energy Switching to the mains is online (〇n-(four) energy saving rather than general, week type 'when there is no time difference between power source switching; 4, no island effect phenomenon; 5, with intelligent wave width scheduling; The problem of the matching of the power quality characteristics is not described. [Embodiment] In order to facilitate the detailed description of the implementation structure of the present invention, the detailed description of the structure, features and functions of the present creation is described below in conjunction with the drawings and the specific embodiments of the present invention. However, this embodiment is only for convenience in explaining the structure of the present creation, and does not impose any limitation on the creation. Please refer to the present invention for the green energy composite power conversion device shown in FIGS. 5 and 6 - the specific embodiment, the conversion device includes There are multiple inputs connecting green and commercial power, direct/straight (DC/DC) converters connected to each input, DC bus module, DC/DC (DC) /AC) Inverter and AC output; the device is designed according to the following operating principle. 'The architecture is the first to provide the same GP Module such as solar energy, wind power, fuel cell, mains, Generally, batteries and the like are connected in parallel to form a multi-terminal input source, and then the electric energy provided by the devices is converted into a DC voltage by a direct/straight (DC/DC) converter, and then sent to a DC bus (DC BUS) module. After detecting the amount of supply by the microprocessor in the DC bus module, the power is converted into AC power through a DC/AC converter and then used for AC Load. In the busbar module, if one of the green energy (such as the solar energy) is weakened, it will be formed by other green energy (using smart shunt technology) or commercial power (C220V/110V)! to the DC/AC converter. After the electric energy is converted into direct current, the power supply is supplied to the DC busbar module, and the energy saving effect of the green energy (the solar energy, the wind energy, the fuel cell, etc.) can be achieved. The DC busbar drainage group is utilized. County has current distribution _ Width modulation (pwM) control technology Μ processing ϋ intelligent ^ shunt, - aspect tracking and speculation of the parallel current between the green energy to adjust the output energy distribution; on the other hand, also detect the total green energy The output is used to adjust the mains H-flow _ so that the DC turn-over can maintain a stable turn-off voltage. In order to achieve a fully online (〇n_Line) grid connection, there is no time difference problem of power source switching. See Figure 6. And in conjunction with Figure 7, the power generated by the pV Array is DC-DC Boost, and is sent to the AC/AC inverter as the main source of energy. If it is a renewable energy source (such as solar energy) When sufficient, it is completely supplied. Once the power supply provided by the PV is insufficient, the DC busbar module will make the power switch (Power Swiich) do the automatic switching action, and the power of the mains by the AC/DC converter. Send to the DC bus module. When the most important thing is to detect the voltage and current of PV and load, it is controlled by pulse width modulation (PWM) control technology, so that the input value of PV can be well controlled. In the implementation of this green energy composite power conversion device, it is also equipped with an external connection M384459 * Liao · Flow Automatic Conversion H (ATS) 'If the power is reduced, the remaining material will be faulty, and the automatic switching will be directly powered by the mains. Further to ensure the power supply of the uninterruptible power supply.凊Continue (4)^图卿' The Weiwei composite power viewing device is in operation's biggest feature is that the voltage provided by the DC busbar module is a stable voltage' but because the DC To AC converter is modulated by pulse width (pWM) It is controlled, so a wide range of changes can be accepted. The power conversion device may have another embodiment, that is, the power switch is removed, and the output voltage of the DC boost (DC T〇Dc B〇〇st) is higher than the voltage of the AC/DC converter by about U5. In this case, when the PV energy is sufficient, it is supplied by the PV. If the PV energy supply is insufficient, the DC output voltage can be lowered, and the AC/DC # is difficult to supply. When the sunshine is sufficient or the load is reduced, the output voltage of the DC boost is increased, and the power is supplied by the pv, which is like the floating ball of the horizontal plane, and the DC balance is maintained, which is the definition of the smart shunt. In the whole system structure, the 'DC busbar module is used as a platform to provide a smart shunt and energy storage, so in addition to PV, 'others such as fuel electric I', wind power, water power, ·.., etc. (4) It can be transferred to the DC busbar module by _'s DC boost (due to the system of each voltage). When the power is off, it can be powered by the external battery (via DC phase) to the DC slave module. In order to complete - online, no islanding effect, can be applied to various renewable energy sources and meet the requirements of other specifications, and consider the application and market demand, we choose 5KVA line composite green energy conversion system.
