Simulation of closed loop controlled current source inverter fed ferromagnetic load

Modelling and simulation of closed loop controlled class D current source resonant inverter (CSRI) for ferromagnetic load is presented in this paper. The converter can operate effectively even for fluctuating source and it operates in zero-current switching mode. The switching devices are connected through a common ground and need only a single DC power supply for the gate driver circuitry. The aim of this work is to develop an induction heater system with minimum hardware. The simulink model of closed loop system is presented. The results of simulation are also presented.
