摘要： A high frequency power supply device has an inverter circuit and an output circuit connected thereto. The inverter circuit includes a diode and a capacitor being connected in parallel to an output side of a switching transistor. A drive input voltage of the switching transistor has a dead time during which a collector voltage thereof is inverted by resonance between the capacitor and a circuit inductance of the device. The switching transistor is turned on when the diode is turned on, thereby reducing the switching loss of the switching transistor. The output circuit includes a ferroresonant circuit or a magnetic amplifier circuit which has a saturable inductor.
