Half-wave voltage regulator for motorcycle magneto

Abstract

The invention discloses a half-wave voltage regulator for a motorcycle magneto. The half-wave voltage regulator comprises an AC side half-wave rectification circuit converting an alternating current generated by a magneto into a negative semi-cycle pulsating direct current, an AC side control circuit controlling an output voltage of the AC side half-wave rectification circuit according to an output voltage of the magneto and a voltage of a headlight of a motorcycle, a DC side half-wave rectification circuit, and a DC side control circuit, wherein the AC side control circuit comprises an AC side synchronization circuit generating a sine wave with same frequency and same phase as the output voltage of the magneto, an AC side sawtooth wave forming circuit generating a first sawtooth wave voltage with same frequency and same phase as a sine wave negative half cycle, an AC side sampling amplification circuit generating a first reference voltage, and an AC side controlled trigger circuit generating a first square wave voltage. In the half-wave voltage regulator for the motorcycle magneto, the voltage of headlight of the motorcycle and the magneto negative half-cycle voltage have the samefrequency and phase, and the AC side motorcycle headlight and the DC side load are controlled independently and are not interfered with each other.

Description

technical field [0001] The invention relates to the technical field of voltage regulators, in particular to voltage regulators for motorcycle magneto. Background technique [0002] Magneto has the advantages of small size, light weight, etc., and is widely used in medium and small displacement motorcycles as the AC power supply on motorcycles, but the voltage pulse output by the magneto is relatively large, so a voltage regulator is needed to stabilize the magneto For the output voltage, the voltage regulator can rectify the alternating current output by the magneto into pulsed direct current to supply motorcycle headlights and loads (including rechargeable batteries) respectively. According to the rectification method of the voltage regulator, the voltage regulator can be divided into half-wave voltage regulation After half-wave rectification, the half-cycle of the alternating current has current output, and the other half cycle has no current output; the full-wave rectific...

AI Technical Summary

Problems solved by technology

In the prior art, because the working voltage waveform of the motorcycle headlights will be short of wave due to some reasons, the short of wave means the wave head is lost, and the lack of wave will lead to the instability of the headlight voltage, so that the headlight flickers

The main reasons for the lack of wave are: 1) The working voltage waveform of the headlight is out of phase with the output voltage waveform of the magneto; 2) The AC side (AC side) headlight and the DC side (DC side) load interfere with each other
