The circuit topology, control strategy, steady principle and characteristic, and design criteria of key circuit parameters of the differential Boost DC-DC converter mode inverter with high frequency link were proposed and deeply investigated. The principle test also was given. This kind of inverter is differentially constituted of two same Boost DC-DC converters with out of phase low-frequency sine pulsate DC output voltage. The research results have demonstrated that this kind of inverter has the advantages such as high frequency electrical isolation, simple topology, bi-direction power flow, small input ripple current, strong adaptability to various loads, high reliability at short circuit. High frequency link＇s inverting technologies theory in power electronics has been broaden and deepen.
