I played around with switch-mode power supply circuits in Qucs-S tonight.
It's interesting how mutli-phase buck converters make almost all problems smaller; smaller/cheaper inductors, smaller output capacitance, smaller transistors required. The only down-side I can see is that the transistors have to be faster or you have higher switching loss.

Swapped my Dreamcast's PSU. Planning on doing a GDEMU install at some point, and while the stock PSU is perfectly good, it being a PAL unit means it doesn't like the 12V rail not being used. The resistor trick in the stock PSU seems a bit unsafe, so decided to replace it with the Robot_Retro unit.

I'm using a uGreen Nexode mini 30W as the AC-DC.

I’m watching a lot of YouTube videos about winding flyback transformers for offline switch-mode power supplies. Almost all of them have a multilayer primary winding. 99% of the videos don’t use any additional insulation between layers and they’re using regular enameled wire, which to me seems dangerous — there is 240V between the ends! #smps #electronics #powersupplies
