Abstract

The invention relates to circuit design for converting AC current output by magneto alternator to DC current with stable voltage through phase shift, clipping and rectification, belonging to technical area of automobile motor and electrical appliances. The circuit design includes single-phase dual half wave controllable rectification loop, voltage signal sample loop and triggering loop of phase shift. Characters are that sample loop composed of R1, R2, R3, DW1, R4, T1, R5, R6, D1, D2 components etc. fetches sampling from voltage output end of magneto alternator directly. The invented device can be utilized as rectifier and stabilizer for charging voltage of magneto alternator brought by micro-mini engine to drive operation of appliances needed DC current or charge accumulators. The stabilizer possesses advantages of simple circuit, reliable operation, good performances and energy saving.

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...
