A Boost Type7-Level Switched-Capacitor Inverter with Reduce Device Count

Abstract

A new SC inverter topology with fewer switching components and lower voltage stress is presented in this research.It comprises merely eight switches and two capacitors, which raise the output voltage by three times the supply voltage to achieve maximum efficiency. The capacitors' voltages are automatically balanced to ensure proper operation. The circuit description, operation, and parameter optimization techniques are presented in this paper. A simple logic-based multicarrier LS-PWM strategyis employed to control the switching operation that reduces the complexity of the control circuit.Furthermore, a comparative analysis with other research topologies has been presented to demonstrate the virtues of this approach. Finally, the proposed topology's verification, feasibility, and effectiveness have been demonstrated both in simulation and experimentation.
