This paper describes the performance and loss analysis of a three-port AC/DC/AC three-phase power converter based on the Japanese 10-15 mode vehicle driving pattern. The structure of the proposed circuit consists primarily of an indirect matrix converter (IMC) and a boost converter connected to the neutral point of the induction motor. The first part of this paper discusses a method for the optimization of the boost converter during single pulse modulation. The authors propose the implementation of feedforward compensation in the boost converter to suppress the battery ripple. Results show that the battery ripple is reduced by approximately 72% during single pulse modulation. The second part of this paper illustrates the behavior of the proposed converter when simulated under the Japanese 10-15 mode driving pattern. Converter losses under different conditions and circumstances are studied, and on the basis of the results, the optimal point of the power control for the converter is discussed.
