Abstract :
A new control scheme for a three-phase/switch/level boost-type rectifier is proposed. The digital-signal-processor-based controller decouples the rectifier into a cascade-connected dual-boost topology within each 60° interval of the line cycle. By taking advantage of the simple structure and that no current sensors are required, it provides an effective solution to applications where high power/low -cost are concerned.
