RECTIFICATION DEVICE AND VEHICLE AC POWER GENERATING APPARATUS PROVIDED WITH SAME

摘要

A rectifier and a vehicle AC generator that can suppress the cost, the rectification loss, and the leakage current from increasing are provided. A rectifier (1) is configured in such a way that in each of n sets, one of a positive electrode side semiconductor device (2) and a negative electrode side semiconductor device (3) is a MOSFET, in such a way that in at least one of the n sets, the other one of the positive electrode side semiconductor device (2) and the negative electrode side semiconductor device (3) is a specific diode, and in such a way that the specific diode is a Schottky barrier diode or a MOS diode, which is a MOSFET whose drain terminal and gate terminal are short-circuited.
