双路电源的主动均流电路系统研究
Research on Active Current Sharing Circuit System of Dual Power Supply
摘要
Abstract
The widely used low-cost power management chips or DC power modules usually do not integrate the output current sharing control function.Therefore,the power output cannot be used in parallel.Using a special power management chip or an additional current sharing control circuit will increase the complexity of the power circuit,resulting in an increase in circuit cost.In view of this application scenario,a dual-channel power switch with active current sharing function is proposed,which is used as a load switch or power multiple-xer.The proposed switch utilizes the switching current method to equally divide the output current,and performs current sharing between the two power sources while hardly increasing the circuit cost.The working principle and parameter design method of the proposed dual-channel power switch are expounded,and the correctness and feasibility of the proposed method are proved through experiments.关键词
