Rectifier bridge circuit for motor car generator, has multiple strands with rectifying elements e.g. Schottky diodes, and protection elements i.e. Zener diodes, connected in parallel to rectifying elements

摘要

The circuit has multiple strands (U, V, W) with rectifying elements e.g. Schottky diodes (S1-S6), Trench MOS Barrier Schottky diode (TMBS), Trench Junction Barrier Schottky diode (TJBS) or field effect transistor, and protection elements i.e. Zener diodes (ZD1, ZD2, ZD4, ZD5), connected in parallel to the rectifying elements. The rectifying elements have low forward voltage. The protection elements have low breakdown voltage as the rectifying elements. Each rectifying element with each parallel connected protection element is integrated in a common semiconductor chip.
