Hi Franklin, Just last week I completed a similar task successfully, so I can get started on this without any ramp-up time. 1) Please confirm DC bus range, expected regen/transients, and SRM phase topology (e.g., 3‑phase 6/4) to size switches, snubbers, and DC link? 2) What specs for the external gate interface: logic level (3.3/5/15 V), isolation, channel count, fault/enable lines, and max command frequency/timing? Suggestion 1: Hardwired protection per phase—isolated drivers with Miller clamp/UVLO, fast shunt+comparator to a latched fault (<2 µs) and deterministic power‑cycle reset—to exceed the 5 µs target. Suggestion 2: Low‑ESL DC link (stacked planes or mini‑busbar with film caps at device leads) plus tuned RC snubbers, on an aluminum baseplate with directed airflow to hold ≤5 °C rise at 4 A. Action Plan: - Phase 1: Lock requirements, ICD, and mechanical fit; finalize test plan. - Phase 2: Schematic, loss/thermal/OCP timing sims; low‑ESL PCB with Kelvin sensing; BOM freeze. - Phase 3: Fab/assembly; bring‑up; verify OCP with pulsed load; LA55P calibration to ±3%; 30‑min 4 A thermal soak; interface docs. - Phase 4: Minor tweaks (if any); final build; acceptance report; pack and ship to Ecuador; deliver Gerbers, BOM, pick‑place, assembly drawings. Best Regards, Sid

@uzairelectronics

Hello, I have carefully reviewed your requirements, and I can deliver this project as a complete assembled, tested, and ready-to-use asymmetric SRM converter platform, not just PCB files. My focus will be to provide a system that you can directly power, connect to the motor, and later interface with your own external controller for gate-command input. I can handle the full scope including circuit design, PCB layout, current sensing with LA55P, fast overcurrent protection, mechanical fit, testing, and final hardware delivery. The design will be developed to meet your acceptance criteria for 4 A continuous operation, thermal stability, sensing accuracy, and protection response. I will also provide all production-ready design and manufacturing files without requiring any further modification. The final unit will be fully assembled, validated, and prepared for shipment to Ecuador for immediate evaluation. A clear and documented external control interface will also be included so you can later implement your FCS-MPC algorithms easily. I have solid experience in power electronics, embedded systems, PCB design, and motor-control hardware development. I would be glad to discuss the specifications and start working on the complete solution. Best regards, Uzair | @engr_uzairpcb
