Abstract :
This paper presents a new topology of the voltage clamped ZVS-PWM high-frequency inverter-fed DC-DC converter designed for a consumer microwave oven to improve line current distortion and power factor in utility AC power side. Its operation principle in steady state is described. The pulse modulation pattern control implementation is discussed under a condition of allowable magnetron current 1.2 A and heater current
