摘 要: A low cost pulse-width modulated (PWM) power unit for electric machines is proposed in this paper. This device consists in a three-phase converter based on a half-bridge configuration, a PWM signal generator, a hardware feedback loop with a Hall-effect current sensor and an adjustable hardware PI controller. Based on a simple mathematical model of the current progress in an inductive load supplied by a PWM power converter, the current response as a function of the PWM duty-cycle, the voltage supply and the other parameters of the electric machine is determined. The performance of the power unit prototype is tested and confirmed by experiments carried out on a direct-drive DC motor (in particular, an ESA 3S by Motor Power Company) and on a direct-drive switched reluctance motor (in particular a YS3040GN501 by NSK).

本文提出一种低成本脉宽调制(PWM)电力装置,用于电动机。该装置由基于半桥结构的三相变流器、PWM信号发生器、带霍尔效应电流传感器的硬件反馈回路以及可调的硬件PI控制器组成。根据PWM电源变流器向电感性负载供电时电流变化的简单数学模型,确定了电流响应与PWM占空比、供电电压及电动机其他参数之间的关系。通过在直接驱动直流电机(特别是Motor Power Company生产的ESA 3S型号)和直接驱动开关磁阻电机(特别是NSK生产的YS3040GN501型号)上进行的实验,对电力装置原型的性能进行了测试和验证。
