基于空间电压矢量控制的单相电机控制仿真分析

s a strong proponent of energy conservation,Inverter technology is also under increasing attention. Study of three-phase motor inverter technology is very mature, while the single-phase motors of relatively small.This paper introduces that single-phase motor is built based on stationary coordinate system and the operating principle of SVPWM control strategy used in a two-phase three-leg inverter. SVPWM algorithm and proposed improvements, the new proposed algorithm is smaller.Finally using MATLAB simulate it dynamically with parameters and give its results. Results show that the current harmonic of the motor is less ,torque ripple is smaller, proving that the use of such controlmethod can achieve the desired effect.
