This paper describes a new modular inverter topology suitable for compact drive systems in electric road vehicles. The topology is based on dc-side cascading of three-phase two-level inverter bridges, each feeding a set of three-phase windings of a motor. This topology is compared by calculation to the known modular high-frequency (MHF) converter, and is found to have similar losses and semiconductor expenditure requirements. Simulations verify the dynamic and static properties of the converter… CONTINUE READING
