Problems solved by technology

Due to the large power gap between the base station in the transceiver state (that is, the state of receiving signals and the state of transmitting signals), it increases the difficulty of power supply for wireless systems, that is, in this case, the load dynamics of power supply equipment (such as power supplies) is large, and the power distribution requirements The average peak power ratio is high, the cost is high, and the output voltage of the power supply equipment fluctuates greatly, which affects the performance of the wireless system

Abstract

The embodiment of the invention discloses a power supply system and a related method, and the system is characterized in that power supply equipment is used for supplying power to electric equipment; the detection circuit is used for detecting the instantaneous load current of the electric equipment; judging whether the instantaneous load current of the electric equipment is greater than the average load current of the electric equipment or not; the control circuit is used for controlling the energy storage circuit to enter a discharge mode to supply power to the electric equipment when the instantaneous load current is greater than the average load current; wherein the power supply electric quantity of the energy storage circuit is determined by the difference value between the instantaneous load current and the average load current; when the instantaneous load current is smaller than the average load current, the energy storage circuit is controlled to enter a charging mode to receive power supplied by the power supply equipment so as to charge the energy storage circuit; wherein the charging electric quantity of the energy storage circuit is determined by the difference value between the instantaneous load current and the average load current. According to the embodiment of the invention, the power supply difficulty of the power supply equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic power, in particular to a power supply system and related methods. Background technique [0002] With the rapid development of communication technology, base stations based on Massive Multiple-input Multiple-output (Massive MIMO) technology (that is, the number of antennas has increased dramatically compared with traditional base stations) have become the main equipment for wireless access. This makes the power consumption of the whole wireless system increase rapidly. [0003] Currently, Time Division Duplex (TDD) in MIMO is a mainstream working mode. In this working mode, the base station (that is, the electrical device) can generate power and send signals to electronic devices (such as smart phones) during the sending time slot; stop generating power and receive signals sent by the electronic device during the receiving time slot. Due to the large power gap between the base station in the ...
