本文介绍了逆变器供电滑差功率恢复驱动器的性能分析和 PSPICE 仿真。该驱动器与其他滑差功率恢复驱动器的不同之处在于，来自转子端子的滑差功率被恢复到将逆变器馈送到电机的直流链路，而在其他方案中，滑差功率被恢复到交流电源。从转子端子到交流电源的滑差功率恢复被二极管桥式整流器阻止，该整流器用于为电机逆变器供电。驱动器的稳态性能分析是在直流和交流数学模型的帮助下完成的。该驱动器的 PSPICE 仿真是使用绕线转子感应电机的等效电路模型完成的。该驱动器是在实验室中为 2 kVA 绕线转子感应电机开发的。理论和实验性能以及模拟结果符合预期。
In this paper, performance analysis and PSPICE simulation of inverter-fed slip-power recovery drive is presented. This drive is different than other slip-power recovery drives in the sense that the slip-power from rotor terminals is recovered to the dc-link of feeding inverter to the motor while in other schemes slip-power is recovered to the ac source. Recovery of slip-power from rotor terminals to ac supply is blocked by diode bridge rectifier, which is used to feed the motor inverter. Steady-state performance analysis of the drive is done with the help of dc and ac mathematical models. PSPICE simulation of this drive is done using equivalent circuit model of the wound rotor induction motor. This drive is developed in the laboratory for a 2-kVA wound-rotor induction motor. Theoretical and experimental performances and simulation results are found as expected.
