Abstract

The present invention provides five phase half-wave rectification voltage stabilizer for car. It contains reference circuit, sampling circuit, trigger circuit and rectifier circuit, wherein sampling circuit respectively connected with reference circuit trigger circuit, sampling circuit connected to rectifier circuit through trigger circuit. It features said rectifier circuit including controllable silicon SCR 1-5 and diode D1-10, wherein controllable silicon SCR 1-5 anode connected together and used as negative terminal of five phase half-wave rectification voltage stabilizer, its cathode connected magneto alternator coil winding JF 1-5terminal through diode D 1-5 connecting trigger circuit, its gate through diode D 6-10 connecting trigger circuit, coil winding JF 1-5 phase differential being 72, five head terminal connect to one point used as anode end of five phase half-wave rectification voltage stabilizer. The present invention samples directly from voltage output end of five phase permanent magnet alternator, through phase shift, clipping, rectifying, converting into voltage stabilization dc current.

Description

technical field [0001] The invention provides a five-phase half-wave 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. 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 for vehi...
