Abstract

This invention provides a car-used six-phase semi-controlled bridge rectification regulator including a primary circuit, a sample circuit, a trigger circuit and a rectification circuit characterizing that said rectification circuit includes thyristors SCR1-6 and diodes D1-18, in which, the anodes of the thyristors are connected together as the negative of the regulator, the cathodes of which are connected to the head of magnet AC generator coil winding JF1-6, the negatives of diodes D1-6 and positives of diodes D13-18, the gratings of which are connected to the negative of diodes D7-12 and the negatives of diodes D13-18 are connected as the positive of the regulator, which samples directly from the voltage output end of a six-phase magnet generator to convert it to the DC current by phase-shift, clipping and rectification.

Description

technical field [0001] The invention provides a six-phase half-controlled bridge rectifier regulator for vehicles, which belongs to the technical field of automobile motors and electrical appliances. Background technique [0002] The output voltage of the permanent magnet alternator changes with the speed change. The output voltage is low when the speed is low, and the output voltage is high when the speed is high. In order to make the output voltage relatively stable, in the existing technology, mechanical resistance method, electronic Short-circuit method, electronic series method, parallel controllable external resistance energy random discharge method and other voltage stabilization measures. For example, the invention patent announced in the Chinese Patent Gazette on December 7, 1988: permanent magnet alternator electronic voltage regulator, application number: 88 1 05250.8, is mainly used for automatic stabilization of the output voltage of permanent magnet alternators...
