Due to the complexity of the structure and control of cycloconverter - type three - phase hf link inverter for soft - switching based on phase - shift - controlled full - bridge mode , a simple and optimized vvvf control strategy is proposed . this control strategy includes : produced pwm by space voltage vector ( svm ) and equivalent carrier frequency fe = 1 / te are introduced into the pdm control of the cycloconverter ; softened equivalent pwm wave is generated at the notches of hf voltage pulses ; the harmonious control between regulating pulse width by phase - shifted angle and regulating voltage of equivalent pwm is to minimize the harmonics content of output voltage of the inverter
西安理工大学博士学位论文针对这种前级移相全桥软开关周波变流型三相高频链逆变器结构和控制的复杂性，提出了一种实现简单而整体优化的vvvf控制策略:将空间电压矢量产生p姗的方法svm和等效载波频率fe = 1 / te引入到周波变流器的pdm控制;按高频电压脉冲前后沿软化等效p翎波;用移相调节高频脉冲宽度和等效p姗调压协调控制逆变器输出电压，在满足输出电压条件下使谐波最小。
