摘要
介绍了空间矢量调制双向开关三相矩阵式变换器的设计和实现方法。空间矢量调制采用输出线电压和输入电流矢量同步调节的控制策略,能实现矩阵式变换器输入输出波形良好的正弦和功率因数为1,并能确保感应电机良好工作。为了实现这种控制策略并把脉冲宽度调制(PWM)波送到相应的开关,采用了数字信号处理技术(DSP)和通用逻辑阵列技术(GAL)。仿真和实验结果验证了这种控制策略的实际可行性。
This paper presents the design and implementation of the space vector modulated 3Φ-3Φ Matrix Converter with bi-directional switches for AC motor is presented.This control strategy,which employs simultaneous output-voltage and input-current space vector modulation,can regulate the input/output sinusoidal waveforms of matrix converter with unity input power factor and ensure the good drive performance of induction motor.In order to implement this strategy and deliver the PWM pulses to the appropriate switches, digital signal processor (DSP) and generic array logic (GAL) are used.Simulation and experimental tests verify the practical feasibility of the proposed control scheme.
