| Abstract: | According to the specialities of DC operation power supply system in power substation,such as high reliability demand,working under heavy load jum p and light loaded operation for long period,a novel system resolution of the high frequency switching power supply based on multi- level monitoring is proposed.Many improvements on the system are achieved through a distributed designed m onitoring system,an inner monitor built in the high frequency rectifier,and the construction of two power topologies in series etc.In this way,the monitoring system works reservedly to im prove the system reliability just as the rectifiers behave,and the power harm onic is greatly reduced,the transient characteristics of the system ,the precision of the output control and system stability are also im proved largely. |
