Designing and bringing up embedded electronics for multi-channel DRSSTC control, with isolated interfaces and an EMI-hardened custom PCB.
Overview
I design and bring up embedded electronics for multi-channel DRSSTC control in a high-dV/dt environment. The system combines an STM32F407 controller, isolated fiber-optic interfaces, timing-critical pulse generation, and a custom four-layer EMI-hardened PCB.
Technical
The board integrates analog emergency-stop circuitry, transient protection, power decoupling, and fiber drivers. I validate the electronics with JTAG and SWD debugging and bench instrumentation, then develop the firmware needed for deterministic pulse generation and multi-channel control. I also support augmented-reality learning modules used to explain electromagnetic concepts.
Tools
Four-layer PCB design, STM32F407, isolated fiber optics, analog protection circuitry, JTAG and SWD debugging, oscilloscopes, logic analyzers, LTspice, C, and Unity-based AR prototyping.
Day-to-day
The work alternates between circuit and PCB design, hardware bring-up, bench validation, board-level debug, firmware development, and integrating the controller into educational research demonstrations.
