Abstract：In the solar array-battery power system of satellites, compared with the conventional power conditioning unit (PCU) that contains three converters, the novel integrated module has such advantages as simpler circuit, more compact and lower cost. However, the control strategy and parameter design of this novel module are very complex. The control strategies for the module operating at different freewheeling methods, which contain domain control and dual-frequency PWM control, are proposed in this paper. Based on the detail analysis of input and output characteristics at different operating modes, parameter design is provided. A 110W prototype is built to verify the theoretical analysis.
