Abstract
Disclosed is a resonant type high frequency power supply device provided with a power element that performs a switching operation, the power supply device including a high frequency pulse drive circuit 1 that transmits a pulse-shaped voltage signal having a high frequency exceeding 2 MHz to the power element to drive the power element, wherein a voltage signal from the high frequency pulse drive circuit 1 is subjected to partial resonance by an impedance of a signal line of the voltage signal and a parasitic capacitance of the power element.
