High-frequency isolation alternating/direct current conversion circuit and control method thereof
A high-frequency isolation alternating/direct current conversion circuit and a control method thereof are disclosed. The conversion circuit includes an alternating current source, a direct current source, a resonant capacitor, a high-voltage energy-storage filter, a high-frequency inverter bridge, a drive circuit, a resonant inductor, a high-frequency isolation transformer, a direct current side synchronous switch, a control circuit, and the like. The conversion circuit is made to be switched between two working modes, a rectification mode and an inversion mode by using a preset direct current source reference voltage as a reference, according to an external voltage reference, and by using different turn-on working modes of the high-frequency inverter bridge.
