We are encountering leakage current problem in power supply, this toroid choke is the reason? Upvote 0 Downvote

Click to expand... You need to define the "leakage current". (Magnitude, AC or DC, which path, is this a safety issue, why is it a problem) Usually a common mode choke is unlikely to cause a leakage current problem. Klaus Upvote 0 Downvote
