【Abstract】 This paper introduces the designing thought of medular constant-current circuits,including the D/A transformation functions,and new-made current regulators. The electrical characteristics of digital-control regulator are analysed theoretically. The results indicate that the regulator is a kind of excellent device with both high stability and wide current range.更多还原
