Control and modulation of the stacked polyphase bridges inverter

In order to meet the requirements of future electric vehicle (EV) drive systems, new converter topologies are required. The stacked polyphase bridges (SPB) inverter is a new topology which is well adapted to the needs for future EVs [1]. In addition to low power losses, the SPB inverter also has fault tolerance ability and good dynamic behavior. This paper presents a further analysis of the control and modulation concept of the SPB inverter. Simulation results are used to verify the analysis conclusions.
