A Quadruplex Boost Switched Capacitor Multilevel Inverter Fed Autoclave Load With Proper Material Selection

In many applications, the cascaded multilevel inverter (C-MLI) architecture is used. However, the primary disadvantage of this kind of inverter is that the C-MLI requires numerous switches and segregated dc sources. As a result, the size, cost, and complexity of C-MLI rises and its efficiency declines. This paper proposes quadruplex boost switched capacitor Half Bridge Cascaded Single Source Multilevel Inverter (SC-HBCMLI) fed induction heated load. In comparison to conventional cascaded bridge inverter 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 level shifted pulse width modulation technique (LSPWM) is adopted. To validate the performance of developed topology, MATLAB simulation and laboratory results are provided.
