a communication power supply

Abstract

The invention discloses a communication power source. The communication power source comprises an alternating-current input module, a solar input module, a first PFC (power factor correction) boosting module, a second PFC boosting module and a PFC monitoring module. The solar input module is connected with the first PFC boosting module, the alternating-current input module is connected with the second PFC boosting module, and the PFC monitoring module is connected with the first PFC boosting module and the second PFC boosting module; the first PFC boosting module is used for boosting output voltages of the solar input module; the second PFC boosting module is used for boosting output voltages of the alternating-current input module; the PFC monitoring module is used for detecting the output voltages of the solar input module and the alternating-current input module, and controlling at least one of the first PFC boosting module and the second PFC boosting module to work according to the output voltages so as to control output power of the solar input module. By the communication power source, solar energy can be utilized fully, energy conversation can be achieved, and occupied space of the communication power source can be reduced.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a communication power supply. Background technique [0002] In recent years, with the rapid popularization of wireless communication, it is necessary to provide communication power for a large number of wireless communication base stations. The communication power of most wireless communication base stations is AC input provided by mains power and diesel generators. Five years ago, the price of photovoltaic solar power panels, the main component of solar energy, was too high, which hindered the application of solar energy. In recent years, especially in 2011, the price of photovoltaic solar power panels dropped by 40%, which greatly reduced the application cost of solar energy. Solar power gradually Applied in communication power supply. [0003] In the prior art, two independent power supplies of AC power supply and solar power supply are used for power supply, and ...

Problems solved by technology

This control method often leads to waste of resources and cannot make full use of solar energy, and the two power supplies are controlled by their own PFC monitoring modules, which also causes the communication power supply to occupy a large space
