To achieve high voltage, low current in the induction heating power circuit, a new control strategy is proposed. This strategy involves using a single-phase NPC three-level inverter with a unipolar frequency-doubling SPWM method.
One of the effective methods used for such needs is the induction heating system. The hard-switching and soft-switching inverters are used in induction heating systems. In this study, the design and analysis of a voltage source series resonance inverter, one of the soft-switching inverters, for induction heating process has been carried out.

T he PWM sw itching control meth od was employed to regulate the output p ower. resonance frequency. The p roposed system proved to be effective for metal treat ment induction heating systems.
Li Sen et al. proposed a bipolar SPWM as the control strategy for the induction heating power inverter circuit. Its inverter circuit has a simple topology, and the control strategy and implementation methods are relatively mature.
