Abstract

The invention provides a voltage regulation circuit, comprising: a rectifier circuit for converting an AC input signal into a DC input signal; a DC-DC conversion circuit connected to the rectifier circuit for voltage regulation of the DC input signal, so that the DC input signal is The voltage of the signal reaches the preset voltage to generate a preset DC signal; the filter circuit connected to the DC-DC conversion circuit is used for filtering the preset DC signal to generate a DC output signal; connected to the feedback circuit of the DC-DC conversion circuit , used to sample the preset DC signal to generate a feedback signal; the PWM control circuit connected between the feedback circuit and the DC-DC conversion circuit is used to adjust the output duty cycle according to the feedback signal, so as to adjust the preset DC signal, so that the The voltage of the preset DC signal is stabilized at the preset voltage. The invention solves the problems of energy waste and short service life of the magneto when the thyristor voltage regulator is used in the prior art.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a voltage regulating circuit. Background technique [0002] Voltage regulating circuit is a commonly used circuit on motorcycles, which is mainly used to convert unstable alternating current generated by motorcycle magneto into stable direct current, which can be used for power supply or load. The existing motorcycle voltage regulating circuit mainly uses a thyristor voltage regulator, which is a power control electrical appliance based on thyristor (power electronic power device) and with a dedicated control circuit as the core. [0003] When the thyristor voltage regulator is used to convert the voltage of the motorcycle magneto, the alternating current output by the magneto is rectified into direct current, and when the voltage of the direct current exceeds the set value, the sampling control circuit sends the voltage to the thyristor. Send a trigger signal to turn it on, so tha...
