Abstract
The purpose of the present disclosure is to protect a power circuit of a base station in a wireless communication system, the base station comprising: at least one module for processing a signal; and the power circuit for supplying power to the at least one module. The power circuit comprises a transformer, a rectifier circuit and a smoothing circuit, and the power circuit reduces the ratio of an on-section of the rectifier circuit if a reverse current from the at least one module is detected.
