摘要

本文提出了一种蓄热或循环发电的方法，用于三电平中性点箝位(NPC)逆变器支腿的热运行试验。该测试确保直流电源只产生损耗，而额定功率在两个支路之间循环，从而最大限度地减少能量浪费。针对NPC逆变器的循环功率测试装置，提出了一种基于比例谐振(PR)控制器的电流控制方案。仿真和实验结果验证了控制器设计在不同工况下的正确性。给出了两种不同工况下逆变器支腿的热测试结果。

Proportional resonant controller based circulating power setup for thermal testing of multilevel inverter

A regenerative or circulating-power method is presented in this paper for heat run test on the legs of a three-level neutral point clamped (NPC) inverter. This test ensures that only losses are drawn from the dc supply, while rated power is circulated between the two legs, thus minimising wastage of energy. A proportional-resonant (PR) controller based current control scheme is proposed here for the circulating power test setup in NPC inverter. Simulation and experimental results are presented to validate the controller design at various operating conditions. Results of thermal test on the inverter legs are presented at two different operating conditions.
