摘要
主电路采用全桥变换拓扑形式,控制电路以UC3825集成控制芯片为核心设计了36V/30A镍氢电池充电电源。为满足充电特性的要求,设计了恒压限流电路及PI调节电路,从而提高了电源的稳态性能和动态性能。设计的过流、过压保护电路,有效地提高了电源的可靠性。
A 36V/30A charging power supply for Ni-MH battery is designed. The main circuit is based on full - bridge converter topology. The control circuit is based on UC3825. The demand of Ni-MH battery charging characteristic is satisfied by using constant-voltage-restricted-current circuit and PI regulation circuit. The steady characteristics and dynamic characteristics of power supply are improved. The reliability of power supply is improved by using over-current and over-voltage protecting circuit.
