초록

A new technique for improving the efficiency of single-Phase high-frequency switch-mode boost rectifiers is proposed. This rectifier includes an additional boost converter that parallels the main high-frequency switching device. The additional converter. which is controlled at lower frequencies. bypasses most of the current in the main switch and the high frequency switching loss is greatly reduced accordingly. The rectifier works cooperatively in high efficiency and as if it were a conventional rectifier with one switching device. The proposed scheme is verified by computer simulation using software PSIM.
