Abstract:Bi-directional inverter with high-frequency link has the advantages such as bi-directional power flow, high frequency electrical isolation, simple topology, few stages of power conversion, and it is especially suitable for occasion in bi-directional power flow. A new-type bi-directional high-frequency link inverters circuit configuration and topology, shifting control strategy, analysis of steady principle, and design criteria for the key circuit parameters are deeply investigated in this paper . The theoretical analysis is verified by the test results.
Keyword:high frequency link inverter phase shifting control bi-directional power flow
