Abstract

The rectifying voltage regulator for mixed power vehicle includes reference circuit, sample circuit, trigger circuit and rectifier circuit, and the sample circuit has input connected to the reference circuit and the voltage output of generator and output connected via the trigger circuit to the rectifier circuit. The present invention features the rectifier circuit including 4 SCR's, SCR1-4, and 8 diodes, D1-8; SCR1-4 with anodes connected together, cathodes connected separately to the tail ends of 4 windings, JF1-4, of the permanent magnetic AC generator and separately via D5-8 to the trigger circuit; and the windings, JF1-4, in phase difference of 90 deg and with four first ends connected in '+' connection to one point. The present invention samples directly from the voltage output of the four-phase permanent magnetic generator and the output voltage is converted into stable DC voltage to drive the power consumers or to charge the accumulator.

Description

technical field [0001] The invention provides a rectifier voltage stabilizer for a hybrid electric vehicle, 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: 88105250.8, which is mainly used for automatic stabilization of the output voltage of permanent magnet alternator for vehi...
