Abstract

The invention discloses a voltage compensation circuit and a power source system with the voltage compensation circuit. The voltage compensation circuit comprises at least two power source chips and at least two switch branches, wherein the switch branches are connected between the power source chips and an output load end in parallel; voltage compensation of different power source chips is achieved through the switch branches. Voltage of the power source chips are supplemented mutually, so that power ripple interference is reduced, the output stability of the power source is improved, and the service life of the power source is prolonged.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a voltage compensation circuit and a power supply system with the circuit. Background technique [0002] With the continuous development of power electronics technology and the continuous improvement of production technology, various electronic products emerge in endlessly. However, the only indispensable thing for electronic products is the power supply, but in addition to providing energy, the power supply products also bring ripples, noise, etc., which affect the normal operation of electronic products. Among them, the ripple voltage will have an impact on circuits such as high amplifiers, local oscillators, frequency mixing, filtering, detection, and A / D conversion. When designing electronic products such as control equipment, electronic instruments, televisions, and cameras, we must find ways to minimize ripple. Ripple is a complex clutter signal. It is a periodi...
