摘　　要：前端采用二极管整流器的六相感应电机驱动系统无法实现再生制动,针对这个问题,提出了一种六相感应电机驱动系统的简易制动方案。不同于传统制动方案需配置额外硬件以消耗制动功率,新型简易制动方案通过控制软件重构实现了在逆变器和电机内部消耗制动功率,避免了制动电阻的使用。新方案基于六相电机驱动系统的额外自由度来增加制动损耗的同时并不会产生转矩扰动。基于六相感应电机驱动试验平台对新制动方案进行了测试。试验结果表明,新方案可在控制器较少变化下实现电机的制动。A six-phase induction motor driving system supplied from diode front-end rectifiers can′t realize regenerative braking. To solve it,a simple braking scheme for a six-phase induction motor driving system was proposed. Different from the traditional braking scheme based on additional hardware to consume the braking power,the simple braking scheme realized the braking power consumption in the inverter and the motor by control software reconfiguration,avoiding the braking resistor. New scheme based on the additional degrees of freedom of the six-phase motor driving system to increase the braking losses without disturbing the torque production at the same time. The new simple braking scheme was tested based on the six-phase induction motor driving system test platform. The test results show that the new scheme can achieve motor braking with less changes in the controller.
