Dual-Output Two-Stage Matrix Converter(DO-TSMC) can achieve bidirectional power flow; the nine-switch inverter stage can drive two loads by two AC outputs; features such as sinusoidal input and outputs, controllable input power factors are all retained. Based on in-depth research and analysis operating principle of the new topology,this paper presents a novel space vector modulation strategy in accordance with proportion coefficient assign action time of each inverter,can achieve the same frequency/different frequency two kinds model output and regulate the output voltage range flexibly; Expressions of input current, DC average current, output voltage and voltage transfer ratio of two inverter stages under this modulation strategy are derived. Finally, through MATLAB simulation verify the correctness, validity and applicability of the novel modulation strategy.
