Switched-Capacitor Embedded Quasi-Z-Source Inverters with Advanced Boosting Capability
2019 IEEE INTERNATIONAL CONFERENCE ON INDUSTRIAL TECHNOLOGY (ICIT)(2019)
摘要
This paper proposes an extended-boosting switched-capacitor embedded quasi-Z source inverter (ESC-EqZSI) topology, which is established by replacing the inductor in the impedance network of the existing active switched-capacitor embedded qZSI (ASC-EqZSI) topology with the switched-inductor (SL) cell, in order to strengthen a boost capability more. It has high boost ability with few components used in the impedance network, and can reduce a voltage stress on the switches of the inverter. A detailed operational analysis of the proposed topology and a comparison with other topologies are described. Simulation and experimental results are present to confirm the effectiveness of the proposed topology.
