A HIGH FREQUENCY FLY-BACK MULTIZONE RESONANT INVERTER WITH AC INPUT SOURCE FOR MULTI-AREA INDUCTION HEATING

摘要

A high frequency fly-back multizone resonant inverter with AC input source for Multi-area induction heating comprising two amalgamated modified flyback converter with equivalent load impedance ZL1 and ZL2 respectively, for converting into a high frequency flyback multizone resonant inverter with AC input source wherein the said first modified flyback converter having load impedance of ZL1 and the said second modified flyback converter having load impedance of ZL2. The said first modified flyback converter comprises of a switch S1, freewheeling diode D1 and modified load impedance ZL1 and the said second modified flyback converter comprises of switch S2, freewheeling diode D2 and modified load impedance ZL2 wherein amalgamated and converted high frequency flyback multizone resonant inverter with AC input source is comprised of equivalent load impedance ZLin connected in series with supply main and another equivalent load impedance ZLS connected parallel with the supply main, a source voltage ‘VS’, a capacitor ‘Cin’ diodes D1, D2, D3 and D4, switches S1, S2 and load impedances ZL1, ZL2, ZL3, ZLin.
