[0001] The utility model relates to the technical field of capacitor compensation, in particular to a compensation circuit based on capacitor. Background Art

[0002] With the continuous development of power electronics technology, electrical equipment has been continuously developed. In order to improve the working efficiency of electrical equipment, a voltage stabilizing circuit is generally used, such as a voltage stabilizing circuit composed of LM317 voltage stabilizer, capacitors and other components, to provide stable and effective electric energy for electrical equipment.
