中文摘要：

对于DC／DC变换器而言．实现DC／DC之间的均流控制是最基本的要求，下垂控制在DC／DC均流控制方面有着广泛应用，但在传统的下垂控制中不可同时兼顾母线电压压降和均流效果。对此提出了一种新的下垂控制方法，该控制中电压输出设定点根据系统的变化而进行动态调整．故在新的下垂控制策略下DC／DC之间在保证均流效果的同时大大降低了母线电压的压降。

英文摘要：

Current sharing is a basic requirement for DC/DC converter and droop control is widely used in DC/DC current sharing.However,in the traditional droop control,it can not give consideration to bus voltage drop or current sharing effet.A novel droop control method is proposed,and the output voltage set-point is adaptively updated with the changing of the system.The proposed method greatly decreased the output voltage drop with significant compro- mise of current sharing performance.
