Input 230V and output Three-Phase 50V 40A SPWM Inverter

Design and build a three-phase, 50 V / 30 A SPWM inverter tailored for an induction motor. The work spans the complete hardware chain—schematic capture, PCB layout, power stage assembly, and gate-drive/protection circuits—plus the firmware that drives it. Either a PIC32 or STM32 can sit at the core; choose whichever lets you deliver stable, low-jitter PWM with minimal dead-time distortion.

Firmware targets
• Closed-loop speed control with a user-selectable frequency range of 0–250 Hz
• Parameter entry and live monitoring over UART, USB, or CAN (pick one to keep the bill of materials lean)
• Safe-start, over-current, and over-temperature trips baked into the interrupt flow

Deliverables
1. Complete schematics (Altium, KiCad, or other mainstream CAD)
2. Gerbers, BOM, and assembly notes for a minimum 2-layer PCB
3. Compiled firmware and fully commented source (MPLAB X or STM32CubeIDE)
4. A brief test report showing the inverter running an induction motor across 0–250 Hz with current up to 40 A

I will bench-test the board on arrival; success is a smooth, sinusoidal line-to-line waveform, adjustable speed under load, and clean fault handling without destructive failures.
