Loading 3D model… large boards can take a moment.
AC power controllers, a 0–10 V industrial dimmer, a digital tachometer and a brushless drive, designed and simulated end to end.

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.

docs/gradateur-0-10V-projet-tutore.pptx: the tutored-project defence for the 0-10 V power dimmer (ENIG, 2024/2025), by Mahmoudi Lassaad, Omri Salim and Dhaoui Chahin. It covers the 7812 supply, the LM358 stage, the PWM power control, the simulation and the PCB. The related boards are kicad/VARIATEUR_0_10V/ and kicad/GRADATEUR_DE_PUISSANCE/.Everything in this repository is my own work.
