Thanks God you had your clothes on. There's reflection in the last photo. Always dangerous...

Great post John.

I agree with Mark, you might want to look at the stability under loading.

While the DC meters may look stable, you might have some interesting signals coming from your circuits.

As for your fan, have you considered a large capacitor and a PWM circuit?

Even at lower voltages, you should be able to drive the DC motor and control the speed with the PWM signal.

the improvement is probably not enough to justify its use in most cases

It might be interesting to see if there is a difference in the ripple and harmonics while using the Mosfets.

One thing that we've always focused on is the Output, but I wonder what is going back to the mains supply with some of these devices.
