High-Power RF supply is developed to drive the current of FRC (Field Reversed Configuration) plasma, which is one of nuclear fusion plasma configurations. By appling the rotating field that is brought by four antennas, plasma current in the toroidal dir ection would be enhanced. The power supply is consisted from the inverter circuit, the step-up tansformer and the LC tank ciruit. The tank circuit is the parallel circuit of the antenna and the capacitor. By the adjustment of the frequency of the inverter output to the resonance frequency of the tank circuit, the large sinusoidal waveform current is obtained.
