摘要

提出了一种新型的PWM功率因数校正(PFC)变换器脉冲调幅(PAM)系统。PAM逆变器的输出可由PFC变换器控制。为了减小感应电动机的转矩脉动，在PAM逆变器中采用了一种新的调制信号。调制信号具有120度的平坦部分。利用所提出的调制信号，提高了基波分量的幅值，降低了开关损耗，使PAM逆变器驱动的电机产生近似恒定的转矩。

A novel PAM inverter system for induction motor drive

A novel pulse amplitude modulation (PAM) system with a PWM power factor correction (PFC) converter is proposed. The output of the PAM inverter can be controlled by the PFC converter. To reduce the torque ripple in the induction motor a new modulating signal is used for a PAM inverter. The modulating signal has the flat portions of 120-degrees. By using the proposed modulating signal, the amplitude of the fundamental component is increased, the switching loss is decreased and the motor driven by the PAM inverter produces approximately constant torque.<>
