摘要
基于开关线性复合(SLH)技术,提出一种新型VVVF功率变换器拓扑结构,目的在于将开关线性复合技术用于异步电动机变频调速领域,从而获得开关线性复合技术固有的优波特性及负载鲁棒性。系统仿真及实验结果表明,该系统在克服电机低速转矩脉动、抗负载扰动特性、抑制PWM高频脉冲对电机的损害方面与传统变频调速系统相比具有明显的优势。
A novel VVVF power converter based on switching linear hybrid （SLH） was proposed. The aim of taking the SLH technology in inductor motor drive fields is to obtain SLH connatural high performances with excellent waveform and load robustness. System simulation and experimental results indicate that for overcoming low speed torque ripple,resisting load disturbance , and suppressing the PWM pulse damage to the motor, the new power converter has advantages over conventional frequency inverter.
