Description

Generator inverter and inverter generator
Technical Field
The application belongs to the field of inverter generators, and particularly relates to a generator inverter and an inverter generator.
Background
When a generator with a large output power is used, the load is three-phase and some are single-phase. The single-phase output power of the traditional three-phase generator is only slightly higher than one third of the total power of the three-phase output, and the rated output power cannot be achieved. The following known patent documents address this problem:
patent document 1: japanese patent application laid-open No. 2010-206904;
patent document 2:201210154043.6 (patent application number);
in the inverter generator described in patent document 1, there is described an inverter control circuit that selectively outputs three-phase alternating current or single-phase alternating current by operating three single-phase inverter circuits of the inverter generator.
In the inverter generator described in patent document 2, the phase synchronous operation method and the output switching method concerning the three-group single-phase inverter circuit in patent document 1 are further improved.
The inverter generator provided in the above document requires single-phase/three-phase switching of the output of the inverter by a control circuit and a switch. When switching to a single phase, three groups of inverters are connected in parallel for output; when switching to three phases, the three groups of inverters perform phase distribution output through data communication. The two above-mentioned literature documents have the disadvantages: the single-phase parallel output and the three-phase output are required to be mutually communicated and cooperated to form accurate phase synchronous operation so as to avoid power consumption among inverters caused by poor synchronization, and each inverter is required to be switched between two working modes of the single phase and the three phases, so that the system design becomes complex, the reliability is possibly reduced, and meanwhile, the control circuits of the whole inverter generator are more in the scheme of the document, so that the design difficulty of the whole machine is increased.

A specific description of the operation of the above-described generator inverter 1 scheme is given below by way of reference to fig. 1 and 2.
In an implementation example, the state switch 104 is used for switching operation of a single three-phase electric output, for example, when the state switch 104 is an on-off switch, the state is on or off, and a state signal of the single-phase electric output or the three-phase electric output is fed back to the first control unit 105 through user operation.
The first control unit 105 detects the working state of the state switch 104;

when the first DC/AC full-bridge conversion circuit 108 outputs a voltage, the second phase detection circuit 113 obtains a reference phase and sends it to the third control unit 114 to trigger the third control unit 114 to detect the DC bus voltage of the third DC/AC full-bridge conversion circuit 112, and when the DC bus voltage is zero, the third control unit 114 does not perform output control.
As described by the above embodiment application examples, the outputs of the first rectifying voltage stabilizing circuit 101, the second rectifying voltage stabilizing circuit 107, and the third rectifying voltage stabilizing circuit 111 are pooled together, and single-phase power is output through the first DC/AC full-bridge conversion circuit 102.
Through the implementation and application examples of the scheme, the generator inverter 1 of the application directly correlates the switching of the state switch 104 with the switching action of the control four-way relay 106, and each control unit works independently, so that a fixed working mode can be formed, mutual interference is avoided, the switching of the output between single-phase full-power output and three-phase full-power output is realized, the reliability of the product is improved, the cost is reduced, and the design difficulty of the inverter generator is greatly reduced.
