In hybrid vehicles, power converters such as inverters and dc–dc converters are installed in the power control unit (PCU). A strong current flows through the inductor of the output filter of the power converter, which causes electromagnetic interference in AM radios and other electrical equipment due to low-frequency noise. In this letter, we attempt to clarify the mechanism of low-frequency magnetic...
When a millimeter wave radar is mounted on a vehicle, it is often installed behind a resin cover, such as an emblem, grill, or bumper. We analyzed the influence of the resin cover on the antenna gain, and clearly showed the mechanism for the degradation of the gain. It was found that a small spacing between the antenna and the cover can improve the antenna gain.
We have proposed the remote controller for the automotive electrical equipment using WBAN. We have studied the transmission characteristic between the transmitting antenna and receiving one. It has been confirmed that the dynamic range between ‘On’ and ‘Off’ is more than 30 dB.
