超音频电源IGBT驱动脉冲重合时间的控制
本文共4页 1972字
摘要：IGBT并联式逆变超音频感应加热电源负载适应性强，频率可达70kHz，功率可达几百千瓦，现已在很多场合取代了SCR中频电源，广泛应用在感应加热领域。主要简述了IGBT并联式逆变器的工作原理。IGBT驱动脉冲重合时间的控制，以及重合时间不足或太长所引发的问题。
关键词：感应加热，电源，驱动／超音频电源
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．
Keywords：induction heating；power supply；drive／ultra—audio power supply
