Abstract

See full text

Apparatus and methods for reducing unwanted conducted noise generated by a DC load 17. Load 17 is powered by a voltage source 11. A current sense 13 senses pulse current Ifan flowing through the load 17. First converting means 14, 15, 16 converts the sensed pulse current Ifan to a correction voltage Vp. The correction voltage Vp is then converted to a correction current Ip, which offsets the deleterious effects of Ifan. The current Is flowing through the voltage source 11 equals Ifan plus the correction current Ip.
