Abstract

In this paper optimal bandwidth of power converters loaded with resonant circuit is defined based on calculations of the switching power losses. Switching power losses in IGBT bridge converters are analyzed depending of the converter’s switching frequency. The operation of a full bridge serial resonant converter for switching frequency below and above the resonant frequency is analyzed. Typical application of such converter with variable resonant frequency is when the converter supplies a device for induction heating of metals. In the paper PowerSim and SemiSiel simulations programs are used. The obtained results are experimentally verified and on their basis an induction heating device for metals is constructed.
