Abstract

In this paper, a novel type time-sharing high-frequency resonant soft-switching inverter composed of combining two-phase multi-resonant sub inverter cells in parallel for common series resonant tank load is demonstrated originally for all metal induction heating cooking appliances, together with a fixed output frequency resonant current phasor angle control scheme by phase-shifted PWM which is suitable for high frequency power regulation. In particular, this high-frequency multi-resonant inverter with lossless snubbing capacitors for ZVS can efficiently operate under the conditions of load resonant frequency changing mode; frequency doubler mode(100kHz) and switching frequency mode(50kHz) for low resistivity metal IH and high resistivity metal IH loads, respectively. The feasible operating performances of experimental setup implementation are evaluated and discussed in detail. The practical effectiveness of this high frequency resonant inverter is confirmed for all metal IH cooking appliances on the basis of simulation and experimental results.
