Abstract
The invention discloses a main circuit of a contactless compensation type voltage stabilizer. The main circuit comprises a compensation transformer and a self-coupling transformer, wherein the self-coupling transformer is connected with the compensation transformer and changes a tap by a controllable silicon; the controllable silicon is connected with a control circuit; and when an input voltage changes, the control circuit sends a control signal to control on and off states of the controllable silicon, and then the tap of the self-coupling transformer is changed, so that an output compensation voltage of the compensation transformer is changed, therefore, an output voltage is kept stable. According to the main circuit of the contactless compensation type voltage stabilizer, the compensation voltage is adjusted by changing the fixed tap of the self-coupling transformer, so that the response speed of the contactless compensation type voltage stabilizer is greatly increased, the reliability of the voltage stabilizer is enhanced and the service life of the voltage stabilizer is prolonged.
