Abstract: PROBLEM TO BE SOLVED: To provide a structure which can control the voltage waveform and current waveform of an output AC power having a rapid response and which increases an extracted power in a power conversion circuit, using a magnetic energy regenerative switch. SOLUTION: A duration of the on-signal of a gate control signal for turning on/off a reverse conducting semiconductor switch constituting the magnetic energy regenerative switch is changed to be within a range equal to or more than the minimum time necessary for a voltage across a capacitor C to reach about 0 [V], due to the discharge of the capacitor C; and the on/off switching frequency of the reverse conducting semiconductor switch is changed within a range equal to or smaller than the resonance frequency determined with the capacitance of the capacitor and the inductance of the resonance frequency inductor 5 to control the voltage waveform and current waveform of the output AC power. Furthermore, a DC power source supplying power to the power converter is connected through a diode to increase an extracted power. COPYRIGHT: (C)2011,JPO&INPIT
