Abstract

Constant frequency power control (CFPC) by phase difference regulation of the gate triggering pulse in the half bridge high frequency inverter (HBHF-INV) is proposed in this paper. The principle of zero current switching (ZCS) operation utilized an overlapping commutation mode in the HBHF-INV is established. The characteristics of the CFPC with ZCS operation are numerically analyzed in associated with normalized frequency and load. The results obtained through the analysis are supplemented with experimental results. Furthermore, design criteria, on the basis of numerical analysis, are investigated.<>
