How to Solve EMI Problems in Isolated Automotive Systems
Electromagnetic compatibility (EMC) has long been a challenge for engineers, and as electric vehicle (EV) and hybrid electric vehicle (HEV) systems continue to gain momentum, this continues to be a major concern. Traditional internal combustion engine (ICE) vehicles are largely mechanical in nature, with electronics bolted to the mechanical power plant. EVs and HEVs, however, are very different. Electrical power is converted into mechanical motion using high-voltage batteries, motors, and chargers. With great power comes great responsibility... to limit the electromagnetic interference (EMI) that comes with power electronics!
