Abstract

In this paper, a family of secondary-side common-mode (CM) noise suppressers is proposed for off-line switching-mode power supplies (SMPSs) used in fault current limiter (FCL). Not only the operation principle of the proposed secondary-side CM noise suppressers is quite straightforward, but also the circuit configuration is extremely simply. Hence, component size as well as cost of the off-line can reduced significantly. An off-line Flyback-type power converter using the proposed CM noise suppresser is analyzed in detail, finally, along with some experimental results to verify the performance and effectiveness of this power supplies.
