High-voltage wiring harnesses that connect an inverter to a motor in a hybrid car need to be designed to suppress electromagnetic emissions that can interfere with other electric devices nearby when alternating currents flow through the wires. To address this issue, we have studied the application of computer-aided engineering (CAE) analysis to the electromagnetic shielding design of these harnesses. This paper reports an example application of CAE analysis to the estimation of noise emissions and discusses the relationships between the electromagnetic field and the voltage or current in the system.
