Team MotorBoard Efficient Motor Control and Power Conversion System Critical Design Review 24 February 2009 Nicholas Barr, Daniel Fargano, Kyle Simmons, Marshall Worth
Purpose and Specifications • Provide a general purpose motor power system and controller • More specifically will be used in the IEEE Future Energy Challenge ‘09 • 30 N-m Cold Torque • 3000 Rpm 3-5 seconds • 1 KW Power • NEMA Frame 56
CrossWorks Code written for Development board using CrossWorks
Power System – Switches • Power MOSFET • high-frequency operation • low-voltage drop (low power losses) • saturation temperature sensitivity • IGBT • low drive current • fast switching time • higher voltage drop (higher conduction losses) • IGBT w/Diode Co-pack • Voltage - Collector Emitter Breakdown (Max): 600V • Current - Collector (Ic) (Max): 85A
Power System – Driver • Configuration: High and Low Side, Independent • Bootstrap circuit designed to prevent gate voltage from dropping below minimum gate threshold voltage
