From the project
4-layer half-bridge motor controller (120 A peak / 40 A continuous, 24 V) designed to replace an off-the-shelf controller on a GreenPower electric race car. KiCad schematic + PCB, isolated gate drive, I²C temperature monitoring.
A custom half-bridge motor controller designed for a GreenPower electric race car, built for the Driven Electric Student Automotive Competition (ESAC) team. Designed to replace the team's off-the-shelf PORTER-10 controller, which limits continuous current to ~10-20 A.
Status: design complete (schematic + 4-layer KiCad PCB), not yet fabricated or bench-tested.
