Title:
車両用の電磁干渉抑制
Document Type and Number:
Japanese Patent JP6858926
Kind Code:
B2
Abstract:
In some examples, an apparatus includes an inverter with a switching circuit. Furthermore, 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. Additionally, a first impedance of a first conductive path to the main ground may be greater than a second impedance of a second conductive path to the main ground. The first conductive path may include the first circuit ground and the first capacitor, and the second conductive path may include the second circuit ground and the second capacitor.
