About
A body of power-electronics design work carried through schematic capture and full mixed-signal simulation before any board was built.
It covers phase-angle AC power controllers (including a capacitive-trigger variant), a 0–10 V industrial power regulator matching the standard control-signal interface used on drives and dimmable ballasts, a microcontroller-based digital tachometer, and a brushless motor drive — alongside characterisation work on transistor stages and power amplifiers.
Simulating first is the point: switching topologies punish the difference between a circuit that works on paper and one that survives a real inductive load.

Questions
How big is the TP3EA PCB?
It measures 24.4 × 26.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TP3EA use?
4 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TP3EA KiCad files?
From the AssaadMH/power-electronics-simulation repository on GitHub, at the commit this page was made from: the board is kicad/TP3EA/TP3EA.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TP3EA design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
