本文介绍了一种采用三电平T型中点箝位（3L-TNPC）逆变器的150 kVA额定功率的电力电子积木式（PEBB）高速电机驱动器相腿的设计和评估。基于模型的预设计评估和电源模块的选择，首先介绍了评估设计的可行性和提高效率。基于选定的功率模块，提出了一种新型的母线结构，杂散电感为11.2 nH。此外，还设计了一种新型非金属冷板，并对其性能进行了评价。它比传统的铝铸造冷板重量轻，共模噪声改善。在文章的最后，进行了连续的测试，以证明所设计的PEBB系统的性能。在开关频率为30 kHz时，测得的最大效率为99.45%，比功率为35.36 kW/kg。
This paper presents the design and evaluation of a phase-leg of power electronic building block (PEBB) with 150-kVA rated power by using 3-level T-type neutral-point-clamped (3L-TNPC) inverter for high-speed motor drives. Model-based pre-design evaluations and power module selections are first introduced to evaluate the design feasibility and improve efficiency. Based on the selected power modules, a novel busbar structure is proposed with a stray inductance of 11.2 nH. Besides these, a novel non-metallic cold plate is designed and evaluated. It shows less weight and improved common-mode noise than the traditional aluminum-cast cold plate. In the end of the paper, continuous tests are carried out to demonstrate the performance of the designed PEBB system. The measured peak efficiency is 99.45% with 30 kHz switching frequency and the measured specific power is 35.36 kW/kg.
