摘要
介绍了混合型级联多电平逆变器的PAM和PWM调制方法,在Matlab7.0中构建了基于这两种调制方法的多电平逆变器的仿真模型。仿真结果表明,混合型级联多电平逆变器能够有效减小谐波畸变率,改善输出电压波形。
This paper introduces PAM and PWM modulate methods of hybrid cascade multilevel inverter, constructs emulational model of multilevel inverter base on these methods in Matlab 7. 0,the emulational results prove that the hybrid cascade multilevel inverter can improve the output voltage wave forms and diminish THD efficiently.
