Description

technical field [0001] The invention provides a DC electronic voltage stabilizer for a permanent magnet AC generator, 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 alternat...
