| Abstract: | This paper describes the design of the high-frequency contravariant current source based on soft switching technology[1].Its feature is to realize the design of constant current source with switching power supply technology,which overcomes the shortcomings of linear constant current source,so it has great practical value.The input voltage is provided by single phase 220V(AC),its output current can be continuously regulated from 10A to 200A,and its output open circuit voltage can be arbitrarily set at the ra... |
