Abstract:
A resonant inverter includes: an input capacitor; an inverter; a snubber circuit; a transformer having a primary winding connected to an AC end of the inverter; a resonant coil, a resonant capacitor, and a current sensor on the secondary winding side of the transformer; and a control unit, wherein, on the basis of current detected by the current sensor, the control unit controls switching elements so as to perform zero voltage switching at the time of turning-on, at a frequency at which a load including the resonant coil and the resonant capacitor becomes capacitive, and performs power regeneration of energy stored in a snubber capacitor to a DC voltage source.

Claim (Index 1):
A resonant inverter comprising:\n an input capacitor and an inverter which are connected to a DC voltage source; a snubber circuit formed by a series circuit of a regeneration resistor and a snubber capacitor, and connected in parallel to each leg of the inverter; a clamp diode connected between a drain of a switching element of the inverter and a connection point between the regeneration resistor and the snubber capacitor of the snubber circuit; a transformer having a primary winding connected to an AC end of the inverter; a resonant coil, a resonant capacitor, and a current sensor connected to a secondary winding of the transformer; and a control unit for controlling the inverter, wherein on the basis of current detected by the current sensor, the control unit controls the switching element of the inverter so as to perform zero voltage switching at a time of turning-on, at a frequency at which a load including the resonant coil and the resonant capacitor becomes capacitive, and performs power regeneration of energy stored in the snubber capacitor to the DC voltage source.
