Domestic induction appliances require power converters that feature high efficiency and accurate power control in a wide range of operating conditions. To achieve this, modulation techniques play a key role to optimize the power converter operation. A softswitching high-frequency resonant inverter for induction heating applications is used here. Three switches are used in this topology, one switch in the high voltage side and two switches in the low voltage side. The working of the circuit is illustrated by adopting the operating principle of the high frequency resonant inverter in periodic switching equivalent circuit mode. The topology is advantageous compared to full bridge topology since the number of switches is reduced in this topology. The switching stresses are also reduced due to the soft switching operation of the circuit.
