发明名称 ACHIEVING ZVS IN A TWO QUADRANT CONVERTER USING A SIMPLIFIED AUXILIARY CIRCUIT
摘要 A zero voltage switch half bridge converter comprises a first and second diode series diodes, parallel with a voltage source. A first terminal of an inductor is joined to the diode junction. A first semiconductor auxiliary switch connected in series between the voltage source and a third diode, which is in series with a fourth diode connected to a second semiconductor auxiliary switch. First and second semiconductor main switches are connected in series and in parallel with the voltage supply. A capacitive voltage divider connected across the voltage source, wherein a second terminal of the inductor is connected to junction of the main switches and a midpoint of the capacitive voltage divider. A control circuit is configured to provide respective control signals to at least the first semiconductor auxiliary switch and the second semiconductor auxiliary switch.
