A power supply for high driving power 5G communication base stations

Abstract

The invention proposes a power supply for a 5G communication base station with high driving power. The power supply for the 5G communication base station includes a PFC circuit connected to the power supply equipment. The PFC circuit includes a power amplifier module, and the power amplifier module drives two MOS transistors through the IC chip to increase the input current. Effectively improve the power factor value under the premise of low cost.

Description

technical field [0001] The present application relates to the field of power supply technology, and in particular to a power supply for a high driving power 5G communication base station. Background technique [0002] The arrival of the 5G era is accelerating. Emerging business models have led to a substantial increase in the energy consumption of communication base stations. Traditional communication power supplies are stretched, and new requirements are placed on the performance and functions of power supplies. Among them, power factor correction PFC (PowerFactor Correction) refers to the relationship between effective power and total power consumption (apparent power), that is, the ratio of effective power divided by total power consumption. Basically, the power factor can measure the degree to which electricity is effectively utilized. When the power factor value is larger, it means that the power utilization rate of the electrical equipment is higher. [0003] Faced wi...
