摘要
对三点式升压型整流器控制提出一种新方法。即在线电压周期的每个60°时限内,以基于数字信号处理器的控制,将整流器解耦成为串联式倍压升压拓扑结构。由于其结构简单,又无需电流传感器,因而有效解决了大功率和低成本应用的问题。
A new control scheme for a three-phase/switch/level boost-type rectifier is proposed.The digital-signal-processor-based con-troller decouples the rectifier into a cascade-connected dual-boost topology within each 60°interval of the line cycle. By taking advantage ofthe simple structure and that no current sensors are required, it provides an effective solution to applications where high power/low-cost areconcerned.
