 		 #93228 - How is this HF generated that radiate.
Responding to: ???'s previous message
Dear Jez,

Thank you so much for your kind reply.

How is this HF generated when switching using a random SSR instead of a Zero crossing SSR? Is their any quantitative relation showing relationship between dv/dt or di/dt and the HF generated that cause emissions and ultimately noise problems.

Regards,
Prahlad Purohit

      Does mean DC switghin = more emission            01/01/70 00:00

            Thats why.....            01/01/70 00:00
