Abstract：The traditional single stage inverters with boost capability are based on output series of DC-DC converters. The boost capacity and efficiency shortage exist widespreadly in this kind of inverters. In this paper a novel output-parallel dual boost inverter is proposed. Opposite to the output series modes the inverter has no direct-current bias and the current flows through less power components when working. When the output voltage is higher than the input voltage only one boost circuit works. The inverter has certain superiority in the boost ability and the efficiency. This paper analyzes the working modes of the inverter and gives out the voltage and current double closed loop control strategy. Simulation and experimental results have verified the analysis above.
