Abstract

The invention provides a three-phase one-half period rectification voltage stabilization type electronic controller, wherein the alternating current exported by the three-phase permanent-magnet alternator is converted to direct current with stabilized electric voltage through phase shift, slicing and rectification, the circuit design includes a three-phase one-half period rectification return circuit, a voltage signal sampling return circuit and a phase shifting triggering circuit. The invention is characterized in that, the sampling return circuit samples directly from the exporting end of the three-phase permanent magnet generator voltage.

Description

technical field [0001] The invention provides a three-phase half-wave controllable rectification and voltage stabilization electronic regulator, 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: 88 1 05250.8, which is mainly used for automatic stabilization of the output voltage ...
