Induction heater is a common technology especially in metal industry. This technology has created a new way of heating metal. It changes the old way (resistance heating) which was more inefficient and more costly operation cost into new way (induction heating) which can provides low operation cost, safer and faster way of heating and higher temperature. The main objective of this project is to create an induction heater controlled by a simple controller. The induction heater is divided into three parts, which are hysteresis controller, switching part and induction part. The induction heater to be made has following specification: Operating frequency at 1 kHz Operating voltage around 10-30V For controller part, hysteresis controller was chosen to be the controller type For switching part, consists of 4 MOSFET as half bridge inverter
