Problems solved by technology

For example, the invention patent announced in the Chinese Patent Gazette on December 7, 1988: electronic voltage regulator for permanent magnet alternator, application number: 88105250.8, is mainly used for automatic stabilization of the output voltage of permanent magnet alternator for vehicles without batteries. The principle of random release of parallel controllable external resistance energy is proposed, which is mainly composed of five parts: load current detection circuit, control switch, threshold voltage control circuit, power switch, power resistor, etc. This method of voltage stabilization adopts parallel controllable external resistance energy random The discharge method wastes energy and the temperature of the electronic voltage regulator rises, and its performance needs to be further improved

Abstract

This invention provides a parallel AC electronic voltage regulator, in which, the circuit of which includes a stabilizing circuit, a voltage signal sample circuit and a load switch circuit and the regulator stabilizes the AC current output by a single-phase magnet AC generator driven by a generator at 12.5V-14.5V via phase shift and chopping.

Description

technical field [0001] The invention provides a parallel AC electronic voltage stabilizer, which belongs to the field of vehicle electrical technology. Background technique [0002] The output voltage of the permanent magnet generator changes with the speed change. When the speed is low, the output voltage is low, and when the speed is high, the output voltage 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: electronic voltage regulator for permanent magnet alternator, application number: 88105250.8, is mainly used for automatic stabilization of the output voltage of permanent magnet alternator for vehicles without batteries. The principl...
