摘要

提出了一种用于交流电机驱动的脉冲比调制电流调节器。该控制方案采用脉冲比调制器(PRM)和线性时变比例加导数(PD)调节器来实现。该方案相当于迟滞电流调节器，但不需要大带宽电流传感器。给出了PRM在静态和动态条件下的数学模型和换相特性。本文报道了3kw交流变频器的仿真结果。

AC current regulator for asynchronous drives with PRM modulator

A pulse ratio modulated current regulator for AC motor drives is proposed. The control scheme is realized by employing a pulse ratio modulator (PRM) and a linear time-varying proportional plus derivative (PD) regulator. The proposed scheme is equivalent to a hysteresis current regulator but does not need a large bandwidth current transducer. The mathematical model and the commutation features of the PRM, in static and dynamic conditions, are presented. Simulation results of 3 kW AC drive are reported.<>
