摘要
介绍了一种新型移相调功高频感应加热电源。逆变电路可以在大的调功范围实现软开关,且只需要一个吸收电容。通过实验对比IGBT模块的关断损耗,证实吸收电容能有效地提高电源的转换效率。转换效率达到了96.4％。
A new high-frequency induction heating power supply with a phase-shifted pulse modulation scheme is introduced. The inverter topology can achieve soft switching commutation in a wide range of power regulation, with only a snubber capicitor. Through experimental measurement of turn-off losses in the IGBT power module, the efficiency gained by using the snubber has been verified. The actual power conversion efficiency reached was 96.4%.
