| Abstract: | Ultra-audio induction-heating power supply based on IGBT parallel inverter can adapt to variable load,whose frequency range can come up to 70kHz and the power can reach several hundreds kilowatt.At present it substitutes for SCR intermediate frequency power supply and can be applied to many fields especially induction-heating industry.The article mostly describes the working principle of the IGBT parallel inverter,the superposition time control of the pulse which can drive IGBT for working and the problem due to the overlong superposition time or insufficiency one. |
