本文介绍了一个统一的参数化机器逆变器设计框架的发展，针对能源效率优化，考虑到最频繁的操作条件和随着时间的推移的功率损耗的积分。以400 V-30 kW的ISG为例，进行了混合动力汽车应用的案例研究。对于3L-ANPC与宽带隙器件，不同的开关频率，不同类型的拓扑结构和PWM策略进行了比较，在逆变器和机器的能量损失。提出了一种考虑逆变器与电机交互作用的电机设计方法。因此，与传统设计相比，所提出的设计具有能量损失的优点。该活动将有助于推动关键应用领域的进展超越最先进水平。
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.
