Description

technical field [0001] The invention relates to a communication base station power supply control device and method, in particular to a communication base station solar DC grid-connected power generation DC-DC special control device and method. Background technique [0002] In the communication system, most of the power supply system in the communication industry adopts the inverter power supply system of alternating current to direct current, and the power supply voltage used by communication equipment is generally limited to direct current within the range of 60v-40v. [0003] At present, there are three types of solar power supply methods for communication base stations, the first is an AC grid-connected photovoltaic system; the second is an off-grid photovoltaic system; the third is a solar power supply system combined with mains power. [0004] The solar off-grid system is a solar power generation system that uses batteries for energy storage and is separated from t...

Problems solved by technology

[0007] In addition, the control equipment of the original solar communication base station power supply system is either a grid-connected inverter or an off-grid controller, which can only work in one working state, when there is mains power or when there is no mains power

The use of solar energy in the above methods is more restricted, energy utilization efficiency is low, and there is a lot of waste.
