Problems solved by technology

The present invention adopts the principle of random release of parallel controllable external resistance energy, and is mainly composed of five parts: load current detection circuit, control switch, threshold voltage control circuit, power switch, and power resistor. The random discharge method of resistance energy wastes energy, and the temperature of the electronic voltage regulator rises, and its performance needs to be further improved

Abstract

The disclosed rectifying voltage stabilizer includes reference circuit, sampling circuit, trigger circuit, and rectifying circuit. Characters are that the rectifying circuit includes controllable silicon SCR1-3, and diode D1-9. Anodes of controllable silicon SCR1-3 connected together are as cathode end of three-phase half controlled bridge type rectifying voltage stabilizer of magneto (TPRVSM). Cathodes of controllable silicon SCR1-3 are connected to initial ends of armature windings JF1-3 of three-phase magneto alternator, connected to cathodes of diodes D1-3, and anodes of diodes D7-9. Grid is connected to cathodes of diodes D4-6. Cathodes of diodes D7-9 connected together are as anode end of TPRVSM. Taking samples from voltage output end of three-phase magneto alternator, the invention through phase shifting, clipping, rectifying operations converts the samples to voltage stabilized DC to drive electric establishment or charge accumulator directly.

Description

technical field [0001] The invention provides a three-phase half-controlled bridge rectifier and voltage stabilizer for a permanent magnet 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. 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 volta...
