| Abstract: | 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. |
