In this paper, a phase shift PWM controlled full bridge-type series load resonant high-frequency inverter is presented for consumer electromagnetic induction heating applications. The bridge arm side link passive capacitive snubbers in parallel with each and AC load side linked active edge inductive snubber-assisted series load resonant soft switching inverter with a phase shifted PWM control scheme is evaluated and discussed on the basis of the simulation and experimental results. It is proved
more » ... from a practical point of view that the series load resonant and edge resonant hybrid high-frequency inverter, including the variable-power variable-frequency regulation function can expand zero voltage soft switching commutation area even under low output power setting ranges. Furthermore, even in the lower output power regulation mode of this high-frequency load resonant tank inverter, it is verified that this inverter can achieve ZVS with the aid of the dual mode control single auxiliary inductor snubber and active edge resonant snubber in HFAC side.
