Abstract

This paper presented three versions of phase-shifted soft-switching PWM with constant frequency or load-adaptive PFM series resonant inverter topologies. Constant frequency phase-shifted inverter is widely used for high power applications. But soft-switching operation is not realized, operating frequency range is limited to around 20 kHz. To introduce load-adaptive PFM control, lossless capacitors, lossless inductors, switching losses and stresses are much reduced and frequency limit is extended more than 100 kHz for IGBTs for example. These inverters are suit for induction-heating applications in metal electroheat processing plants, food cooking processing plants, hot water and hot gas producing processing plants.
