Abstract

This invention provides a four-phase half-control bridge commutation regulator used in cars including a primary circuit, a sample circuit, a trigger circuit and a commutation circuit characterizing that the comutation circuit includes thyristors SCR1-4 and diodes D1-12, in which, the anodes of the thyristors SCR1-4 are connected together as the negative end of the regulator, the cathodes of which are correspondingly connected with the head ends of JF1-4 of permanent AC generator coil windings and the negatives of the diodes D1-4 and the positives of the D9-12, the gratings are connected with the negatives of diodes D5-8 and the negatives of diodes D9-12 are connected together as the positive end of the regulator, which directly samples from the voltage output of the generator to convert it to DC of stabilized voltage by phase shift, clip and commutation to drive devices needing DC working directly.

Description

technical field [0001] The invention provides a four-phase half-controlled bridge rectifier regulator for automobiles, 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. Such as the invention patent announced on December 7, 1988 in the Chinese Patent Gazette: permanent magnet alternator electronic voltage regulator, application number: 88105250.8, which is mainly used for automatic stabilization of the output voltage of permanent magnet alternat...
