摘要：

In this paper, we present a buck-boost-full-bridge (BBFB) inverter that is a novel circuit topology developed for all-metals induction heating cookers. A power device of a full bridge inverter serves as a part of the H-bridge PAM (Pulse Amplitude Modulation) converter, thus reducing the number of power devices. In iron pan heating, it consists of a buck converter stage and a full bridge inverter stage with a boost function. On the other hand, in aluminum pan heating, it completely becomes independent of the H-bridge PAMconverter stage and a single-ended push-pull (SEPP) inverter stage. For iron pan heating, the power conversion efficiency showed an approximately flat characteristic in a wide power range.
