Sapana Sharma, V N Patil, 2023. "A High-Resolution Single-Source Three-Phase Switched-Capacitor Inverter with High Voltage Gain" ESP Journal of Engineering & Technology Advancements 3(1): 92-97.
A novel three-phase switched-capacitor (SC) topology is proposed in this paper. A seven-level line-to-line output voltage waveform is generated by the fundamental structure of the proposed topology, which includes eight switches and two capacitors, per phase leg. The proposed topology has several main features, including increased boost capabilities, lower voltage stresses, and a minimum number of device counts. Switched capacitors also have built-in capacitor voltage balancing, eliminating the need for a separate balancing circuit. The modulation technique is used to keep the capacitors self-balanced for all values of the modulation index. In this paper circuit description, mode of operation, and modulation strategy is discussed thoroughly. Lastly, simulation results are provided to validate the feasibility of the proposed inverter.
