Low Emi

Posted by: koksalocal on

I just wonder why PI Expert 7.0 sowtware advise the connection of cathode side of the output diodes to the transformer in the transformer construction section for lowest emi.(Normally we conect the anode side of the output diode to the transformer)

We will be very pleased if some explanation for the advise is made?

Best Regards...

The only reason is that in some designs it is easier to design shield windings if the secondary side diode is connected on the return leg of the secondary (cathode connected to transformer)
