The grid voltage of commercial utility power source in Japan and USA is l00rms, but in China and European countries, it is 200rms. In recent years, in Japan 2G0Vrms out putted single phase three wire system begins to be used for high power applications. In l00Vrms utility AC power applications and systems, an active voltage clamped quasi-resonant inverter circuit topology using IGBTs has been effectively used so far for the consumer microwave oven. In this paper, presented is a half bridge type voltage-clamped high-frequency inverter type AC-DC converter using which is designed for consumer magnetron drive used as the consumer microwave oven in 200V utility AC power system. This zero voltage soft switching inverter can use the same power rated switching semiconductor devices and three-winding high frequency transformer as those of the active voltage clamped quasi-resonant inverter using the IGBTs that has already been used for 100V utility AC power source. The operating performances of the voltage source single ended push pull type inverter are evaluated and discussed for consumer microwave oven. The harmonic line current components in the utility AC power side of the AC-DC power converter operating at ZVS-PWM strategy reduced and improved on the basis of sine wave like pulse frequency modulation and sine wave like pulse width modulation for the utility AC voltage source.
Index Terms; Zero Voltage Soft Switching Inverter, High Voltage Transformer, Voltage Doubter, Non smoothing LC Filter, New Pulse Pattern Modulation.
