Title:
ELECTROMAGNETIC INTERFERENCE SUPPRESSION FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/182132
Kind Code:
A1
Abstract:
According to several embodiments, a device includes an inverter having a switching circuit. In addition, a first circuit has a first circuit ground and a second circuit has a second circuit ground. For example, the second circuit may be electrically connected to the switching circuit and the second circuit ground may be electrically connected to the first circuit ground. A first capacitor may be electrically connected between the first circuit ground and a main ground. In addition, a second capacitor may be electrically connected between the second circuit ground and the main ground. In addition, a first impedance of a first conductive path reaching the main ground may be greater than a second impedance of a second conductive path reaching the main ground. The first conductive path may also include the first circuit ground and the first capacitor, and the second conductive path may also include the second circuit ground and the second capacitor.
