An Adaptive Control Applied to Series Resonant Inverter for Induction Heating

An adaptive linear quadratic regulator of a cascade buck chopper-full bridge inverter is presented. A full bridge series resonant inverter based on zero-voltage switching (ZVS) and an adaptive control is used as a power supply for induction heating. An adaptive control does not only keep the output current and the voltage in phase but also makes the system operating in zero-voltage-switching mode for constant and variable load
