| 摘 要： | 本文论述了电流逆变器换流电容和感应电动机漏感抗之间的能量转换产生的尖峰电压叠加在基本电压之上,引起换流电容、半导体元件、电动机绝缘承受很高的电压,为减小尖峰电压,电动机应有小的漏电抗。电流型逆变器供电的电动机的设计不仅是最优漏抗问题,它的设计和普通电动机不同,应使整个拖动系统成本最低,其特性适合特殊要求。

| Abstract: | This paper discusses a high vqltage subjected to commutation capacitors, semiconductors and machine insulation.The high voltage resulted from the summation of the original voltage and the voltag spikes which produced from the energy exchange between the commutation capacitors of the current source inverter and the leakage inductance of a motor.To reduce the voltage spikes, a moter should have a small leakage reactance.The design of a CSI-fed motor, differing from a conventional-fed motor, is not only an optimum leakage problem but minimizing the cost of the overall system and satisfying specified performance required as well |
