可提高放电效率的充放电控制电路

A Charge and Discharge Control Circuit to Promote Discharging Efficiency

在不间断直流稳压供电系统中,蓄电池的充放电控制是保证负载在断电后能否正常工作的关键。本文介绍了一种新颖的充放电控制电路,它能在断电后使蓄电池在安全规程要求下可靠供电2h。电路结构简单,充放电效率高,蓄电池能可靠、安全的重复使用。

In an unintermitted DC regulated power supply system, the charge and discharge control of the batteries is a key of guaranteeing the normal working of the load after the power is cut off. The article introduces a new charge and discharge control circuit with which the batteries remain supplying 2 hours after the power is cut off according to the requirements of safety rules and regulations. The circuit has simple structure and high efficiency of charging and discharging, thus the batteries can be reliably and safely repeated for use. 
