| 摘 要： | 针对单相单开关三电平(VIENNA)整流器提出了新的简单模拟控制方案.该方案以单周期控制技术为基础,结构简单,无需R-S触发器.在实现较高输入功率因数的同时,仅用单个电压环即可实现直流侧电压的稳定以及电容电压的均衡.介绍了采用简单模拟控制方案的单相VIENNA整流器实现高功率因数运行的工作原理,给出了控制方程和具体实现方案.阐述了变换器实现电容电压均衡的工作机理.仿真和实验证明了理论分析的正确性,以及控制方案的可行性.

| Abstract: | Aimed at single-phase VIENNA rectifier,a new simple analog control scheme is proposed.The scheme is based on one-circle control is simple,and can improve the stability of the controller without the S-R flip-flop.Only using one voltage loop,the stabilization and balance of the output voltage and higher input power factor are realized.The principle of the realization of high unity power factor of the single-phase VIENNA rectifier based on simple analog control is analyzed.Some control equations and implementa... |
