Abstract :
Experiments were conducted to determine the optimum load impedance of full-bridged MOSFET power inverters of the voltage-fed type operating at 1.0 MHz to 2.5 MHz. The DC-to-RF power conversion efficiency was 74.3% and the RF output power was 572 W at 1.0 MHz when the load impedance was optimum at 25.0 Ω and when the DC input voltage was 140 V. The DC-to-RF power conversion efficiency was 71.8% and the RF output power was 955 W at 2.5 MHz when the load impedance was optimum at 12.5 Ω and when the DC input voltage was 140 V
