The upper left tube and the lower left tube form a left half-bridge, the upper right tube and the lower right tube form a right half-bridge, and the midpoint of the left half-bridge and the midpoint of the right half-bridge are connected to the output end of the high-frequency transformer. The upper left pipe and the upper right pipe form an upper bridge, the lower left pipe and the lower right pipe form a lower bridge, the upper bridge is connected to the positive output end, and the lower bridge is connected to the negative output end.
The active clamp bridge comprises four structures: four controllable pipe bridges, three controllable pipe bridges, two controllable pipe bridges and a single controllable pipe bridge. As shown in fig. 4, the four-controllable-tube bridge circuit is a four-controllable-tube bridge circuit, wherein all four tubes in the four-controllable-tube bridge are switching tubes; as shown in fig. 5, the circuit is a three-controllable-transistor bridge circuit, in which three transistors are switching transistors and one transistor is a diode; as shown in fig. 6, the circuit is a two-controllable bridge circuit, in which two transistors in the two controllable bridge are switching transistors and two transistors are diodes; as shown in fig. 7, the single controllable transistor bridge circuit is a single controllable transistor bridge circuit, in which one transistor is a switching transistor and three transistors are diodes.

Fig. 9 shows an active clamp type high frequency chain inverter circuit according to an embodiment of the present invention, in which the primary side conversion circuit is a full bridge inverter circuit, and the active clamp circuit is a four-controllable full bridge and a clamp capacitor. A simulation model of the active clamp type high-frequency chain inverter circuit is built on a PLECS simulation platform, the adopted modulation strategy is shown in fig. 10, fig. 11 is a partial enlarged view of fig. 10, and simulation parameters are shown in table 1.
TABLE 1 simulation parameters
As can be seen from fig. 10 and 11, the primary side conversion circuit outputs a high frequency square wave (u)cd) And is synchronous with the carrier wave, so the high-frequency transformer has no magnetic bias and is beneficial to the design of the transformer. At the same time, in one switching period, the secondary side converting circuit outputs (u)xy) Correspondingly outputting two modulation pulses, which shows that the lowest harmonic of the output SPWM wave is twice the switching frequency, and is beneficial to the design of a low-pass filter.
As shown in fig. 12 and 13, the simulation results are the simulation results of the active clamp function not used and the active clamp function used, and respectively show the clamp capacitor voltage waveform and its locally amplified waveform, the secondary side converter output voltage waveform and its locally amplified waveform, the load voltage waveform, and the device withstand voltage waveform. When the active clamping function is not used, voltage spikes occur due to the existence of leakage inductance of the high-frequency transformer, and as can be seen from the output voltage waveform of the secondary side conversion circuit and the partially amplified waveform thereof in fig. 12, the voltage at the spikes is up to twice the value of the secondary side voltage of the transformer. As can be seen from the device breakdown voltage waveform in fig. 12, the device breakdown voltage is a peak voltage, which seriously threatens the safety of the switching device and reduces its available capacity.
When the active clamping function is used, as can be seen from the clamp capacitor voltage waveform and its locally amplified waveform in fig. 13, the average value of the clamp capacitor voltage is the secondary side voltage of the transformer, and the voltage fluctuates up and down due to absorption of peak energy and feedback energy to the input end, and the fluctuation amplitude is about 8V. As can be seen from the output voltage waveform and the local amplified waveform of the secondary side conversion circuit in fig. 13, the leakage inductance energy of the high-frequency transformer is absorbed by the active clamp without loss, and the voltage spike is eliminated. As can be seen from the device withstand voltage waveform in fig. 13, the device withstand voltage is the secondary side voltage of the transformer, which is beneficial to improving the safety of the switching device and improving the available capacity of the switching device. As can be seen from the load voltage waveforms in fig. 12 and 13, the load voltage peak is 640V, which is the same as the theoretical full-bridge output voltage (400V × 2 × 0.8 — 640V).
Compared with the invention patent application CN108566097A, the simulation results obtained by using the same parameters as those in table 1 are shown in fig. 14, which respectively show the clamp capacitor voltage waveform and its local amplified waveform, the secondary side conversion circuit output voltage local amplified waveform, the load voltage waveform, and the device withstand voltage waveform. First, as can be seen from the clamp capacitor voltage waveform and its locally amplified waveform in fig. 14, the average value of the clamp capacitor voltage in the solution of the invention patent application CN108566097A is the secondary side voltage of the transformer, and the voltage fluctuates up and down due to the absorption of peak energy, filter inductance energy and feedback energy to the input end, the fluctuation amplitude is about 80V, which is 10 times of the fluctuation amplitude of the clamp capacitor voltage of the invention, and if the fluctuation amplitude is to be reduced, only the capacitor capacitance is increased, which will result in the increase of cost and volume. As can be seen from the partial amplified waveform of the output voltage of the secondary side conversion circuit in fig. 14, in the solution of the invention patent application CN108566097A, there is no voltage spike, and the high level voltage value is the secondary side voltage value of the transformer. As can be seen from the load voltage waveform in fig. 14, the peak voltage of the load voltage in the solution of the invention patent application CN108566097A is 320V, which is half of the peak voltage of the load voltage in the invention. As can be seen from the device withstand voltage in fig. 14, the device withstand voltage in the solution of the invention patent application CN108566097A is the secondary side voltage of the transformer.
As can be seen from comparison between fig. 13 and fig. 14, when the same device has the same withstand voltage under the same parameters, the clamp capacitor of the present invention has the advantages of smaller requirement, low cost and small volume; the output load voltage is twice of the inventive patent application CN108566097A solution, so the output capacity of the present invention is also twice of the inventive patent application CN108566097A solution. When the output voltage is the same, the voltage resistance of the invention is half of the scheme of the invention patent application CN108566097A, therefore, the invention can select a device with lower voltage resistance and has low cost; meanwhile, the device with low voltage resistance generally has stronger current capacity, so the output capacity of the invention is also higher than that of the invention patent application CN 108566097A.
