Hi,

I have problem with a circuit i have designed uses a linear power supply with a transformer 220-12 VAC 1A , when i measure on any point on the circuit with respect to the earth point i found 110 VAC on the scope. I need to know why i see this 110 VAC or this is due to the transformer interwinding capactance, if it's so how i can remove this signal from my circuit. I think that this is a common mode signal.

Waiiting your reply
With my best regards
