| Abstract |
This paper presents the development of a unified parametric machine-inverter design framework targeted at energy efficiency optimization that is taking into account the most frequent operational conditions and the integral of the power losses over time. A case study is conducted with 400V-30kW ISG in hybrid electric vehicle application. For 3L-ANPC with wide band gap device, various switching frequencies, and different type of topologies and PWM strategies are compared with respect to energy loss in both inverter and machine. The machine design methodology is presented considering interactive effect between inverter and machine. As a result, proposed design has an advantage of energy loss compared to conventional design. The activity will contribute to drive progress beyond state-of-the-art in key application domains. |
