Electromagnetic Interference (EMI) in AC motor drive
Fast switching currents in insulated gate bi-polar transistor (IGBT) module
PCB coupling paths to the cables and motor
Causes device failure
Meet government limits
Costly to diagnose late in design cycle
Create a circuit model (SPICE) of the EMI coupling paths in the drive including:
the IGBT package (L and C)
the cables and motor measurements and modeling
Shielded & unshielded cable
Document and demonstrate the processes involved for EMC design
Demonstrate mitigation opportunities for EMC design and discovery
C = 39.4 pF
