Implementation of Three Phase Induction Heating By Using Half Bridge Series-Resonant Inverter Topology

Today most of domestic induction heating technology functions on a single-phase power due to the limited quantities of cooking material being heated. While on other hand in most of the industrial environments, where the larger cooking material volumes are processed, heat generation intensifies. Hence three phase power comes into picture, by which we can achieve the resonant frequency for achieving the desired heat generation. Resonant-mode power supplies can minimise switching losses, enabling the operation of resonant converters at exceptionally high frequencies. The inverter operates at in a frequency range of 20-30 kHz. Industrial induction heating technology also requires a high output power levels with the minimum number of components in a compact size. In this paper, an induction furnace that is employing with half bridge inverter built around the pair of (Insulated Gate Bipolar Transistor's) IGBT's as its switching device. High frequency converter to convert the constant DC to the high frequency AC by switching the devices (IGBT's) alternately. The simulation implementation of this topology with the help of MATLAB/ SIMULINK environment.
