摘要
利用双向DC/DC变换器电路,实现了不间断电源(UPS)蓄电池充放电系统中能量的双向流动及直流总线电压的稳定,从而提高了系统效率;通过添加耦合电感,使DC/DC变换器具有高升降压比,从而减少了铅酸蓄电池的单体个数,降低了UPS系统的总成本。在此,分析了一种带耦合电感的双向DC/DC变换器电路;详细分析了变换器的工作原理和主电路参数设计,通过仿真与实验验证了该方案的可行性。
In the UPS accumulator cell charge-discharge system, two way flow of energy and stabilization of DC bus voltage was realized by the bi-directional DC/DC converter circuit with coupled inductors,which can improve system efficiency. The coupled inductors was used,which makes converter with high conversion ratio,cut down the lead acid storage battery number and decrease the cost reduction in UPS.A kind of the bi-directional DC/DC converter circuit with coupled inductors is proposed, and the principle of the converter circuit and the main parameters are analyzed.Simulation and experiment result prove the scheme is feasible.
