Various electronic devices are now mounted in vehicles. These automotive devices contain power circuits in order to create the voltages required to power these devices.
The power circuits use a switching system that increases efficiency, but is also a source of problematic noise. Noise suppression measures for the power circuits (DC-DC converter) of devices mounted in vehicles are described below.
The noise suppression measures and products introduced here are not limited to vehicles and can also be used with industrial and other equipment.
