摘要

本文研究了采用表面贴装永磁同步电机或带电压源逆变器的鼠笼式感应电动机的大型交流驱动系统的改进PI电流控制结构。为了降低半导体器件高频开关造成的功率损耗，采用了多种补偿方法，并提出了一种改进的PI电流控制器结构，在驱动器工作频率相同的情况下，降低逆变器的开关频率。为了证明控制程序的功能，给出了仿真、实验开发和测试结果。

Compensation methods applied in current control schemes for large AC drive systems

The paper deals with modified PI current control structures for large AC drive systems which use surface mounted permanent magnet synchronous machines or squirrel-cage induction motors supplied with voltage source inverters. In order to reduce the power losses caused by high frequency switching of the semiconductor devices, various compensation methods are used and a modified structure for a PI current controller is proposed, to reduce the switching frequency of the inverter for the same operating frequency of the drive. Simulation, experimental development and test results are presented in order to demonstrate the capabilities of the control procedure.
