Description

technical field [0001] The invention provides an electronic voltage stabilizing controller for a hybrid excitation generator, which belongs to the technical field of automobile motors and electrical appliances. Background technique [0002] The output voltage of the 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...
