摘要
结合单相H桥和三相桥式变流器等电压型主电路拓扑所共有的半桥单元电路模型,通过研究其滞环电流跟踪控制的物理过程,对其开关频率的影响因素进行理论分析,得出有关滞环控制开关频率的计算公式和定量分析方法。
Integrated single-phase H bridge and three-phase bridge converter voltage type main circuit topology in half bridge circuit model, analyzed the theory about its affect factors of switch frequency by research the physics process of hysteretic current track control, draw the formula and quantitative analysis method about hysteretic control switching frequency.
