A Switched Capacitor Inverter Structure with Hybrid Modulation Method Lowering Switching Loss

The high-frequency modulation method (HFM) for a switched capacitor (SC) inverter often leads to high switching loss since it increases frequency. In order reduce the frequency and in HFM SC inverter, this paper proposes novel hybrid strategy as well corresponding demo topology. limits number of switches, thus reducing significantly. Meanwhile, topology maintains merits current such low switch count, quadruple voltage-boosting ability self-balancing capacity. principle circuit configuration are analyzed detail. And comparisons introduced demonstrate advantages proposed Finally, experimental results have proved feasibility inverter.
