The Low Power Induction Heating Using Resonant Technique

A simple low power portable induction heating controller circuit based on resonant technique is presented. The controller is developed using Peripheral Interface Controller (PIC) and Insulated Gate Bipolar Transistor (IGBT) as the main switching devices. The laboratory model of the system is developed and tested as a portable cooker with DC power supply. The performance of the cooker is compared with the conventional hot plate technique. The proposed system is also applicable with AC power supply. Simulation results with an AC supply show the proposed technique is able to produce high frequency output current with less harmonics distortion injected back to the AC supply.
