N2 - This paper represents the practical evaluations of time-sharing high-frequency resonant soft-switching inverter composed of two multi-resonant sub inverter cells in parallel for common series resonant load for all metal induction heating (IH) cooking appliances. Together with a fixed switching frequency resonant current, IH power regulation is carried out by phasor angle control scheme with phase-shifted PWM scheme. In particular, this high-frequency multi-resonant inverter can efficiently operate under the conditions of load resonant frequency changing mode; frequency doubler mode (100 kHz) for low resistivity metal IH loads and fundamental switching frequency mode (50 kHz) for high resistivity metal IH loads, respectively. The feasible performance of the time-sharing high-frequencys inverter are demonstrated and discussed in detail.
