摘要

本文研究了用于控制非对称两相异步电动机转速的正弦脉宽调制(SPWM)四支路电压源逆变器的设计与构造。正弦型PWM开关信号由ARM7 (Adu7024)微控制器产生，该微控制器可编程且价格低廉，同时产生开关信号的频率高。两个icIR2130用于电机驱动部分。输出电流信号的特性几乎接近正弦模式，从而提高了电机控制的效率。为了控制异步电动机的转速，采用PI闭环控制技术控制电压频率比(V/f)并获得恒转矩。

Asymmetrical two-phase induction motor speed controlled with 4-leg voltage source inverter

This research is design and construct of Sine Pulse Width Modulation (SPWM) 4-leg voltage source inverter for controlling speed of asymmetrical two-phase induction motor. The Sine PWM switching signal is generated by ARM7 (Adu7024) microcontroller which is programmable and cheap, while having high frequency to generating switching signal. Two ICs No. IR2130 are used for motor driving part. The characteristics of output current signal are nearly closed to sinusoidal pattern resulting to high efficiency for motor control. In order to control the speed of induction motor, ratios of voltage to frequency (V/f) are controlled and constant torques are obtained by implementing technique of PI close-loop control.
