单级高频链固态变压器拓扑及其优化控制研究

This article proposes a new single-stage high-frequency-link based single-phase solid-state transformer (SST) topology. Switching tube multiplexing is carried out to reduce the number of switching devices and the corresponding modulation strategy is given. An optimized hybrid control analysis for reducing the average conduction current of insulated gate bipolar transistor (IGBT) and inductor was p...
