Abstract
In this work, a hybrid switched capacitor multilevel inverter (SCMLI) based induction heating (IH) system, which combines multilevel inverter (MLI) and autoclave load is proposed to enhance the performance of the system for IH applications. The primary disadvantage of MLI is it requires numerous switches and dc sources. As a result, the size, cost, and complexity of MLI rises, and its efficiency declines. To overcome this issue SCMLI is considered to fed the autoclave load. In comparison to conventional MLI the proposed topology utilizes less number of components with boosting capability. Moreover this topology offers lower harmonic distortion and higher efficiency. To provide the gate signals to the switches phase disposition pulse width modulation technique (PDPWM) is adopted. Also the mathematical modelling of the litz wire based coil is performed to calculate the accurate resistance and inductance of the coil. To validate the performance of hybrid system, MATLAB simulation and laboratory results are provided.
