Abstract
In a power converter, a housing is grounded. A power converter circuit is installed in the housing and configured to perform power conversion of input power into output power. An external terminal is electrically connected to the power converter circuit for connection of an external device to the power converter circuit. A first capacitor has first and second electrodes. The first electrode of the first capacitor is connected to the external terminal, and the second electrode thereof is connected to the housing. A second capacitor has first and second electrodes. The first electrode of the second capacitor is connected to the external terminal, and the second electrode thereof is connected to the housing. The first capacitor, the external terminal, the second capacitor, and the housing is arranged to provide a conductive loop.
