Design Overview Electric Drive System for mid-size passenger vehicles 100kW-200kW (130-250 HP) FPGA based all digital control Screen with UI for real-time status display (RPM, temperature, battery life, etc.)

PCB Design Constraints EMI from high current rails Logic & analog voltage supplies 1.2, 2.5, 3.3, 5, 18 PCB Size & Form Water cooling tubing, power rail connect points Circuit placement Switching components, logic power supply, logic circuitry, analog feedback High density of FPGA

PCB Layout – Logic Power Supply

PCB Layout – Gate Drivers Minimize parasitic inductances, loop area

PCB Layout – IGBT Pair Placement 180°Switching pairs placed closest to each other Reduces length travelled by high frequency currents

PCB Layout – Motor Drive Board
