Default B Field collapse

In common power supplies the only example where there might be a problem would be that using choke input. The choke likes to keep the current flowing, so a switch between the rectifiers & the choke input could cause insulation failure. But a switch on the primary side as it normally would be is OK, the choke still has a way to dump stored energy thru the PS transformer wdgs & rectifer.

But choke input is now uncommon, most PS are cap input.

In my case I installed the fix I spoke of in a regulated PS with DC standby I built many years ago so that it can be run either in choke or cap input. The max volts or current can then be used to advantage.

Cheers to all, John L Stewart
