摘　　要：　选择了一种"恒流"驱动电路,采用并联冗余,在不增加外部控制电路的情况下,能确保各并联支路的电流自动平均分配,使均流和冗余技术融为一体。当其中一路出现过载、短路时,热熔保险迅速熔断,使这一路断开冗余组件,其余支路又自动均流。提高了系统的可靠性。A kind of invariant current driving circuit is selected and the technique of parallel connection redundancy is used.Without an additional exterior control circuit,it can insure that each multiple connection can get wellallocated current automatically.When one of them appears to be in overburden or shortcircuit,the fuse will quickly break the redundant circuit,while the rest derived circuit can automatically share the wellallocated current,thus improving the reliability of the system.
