Abstract
A vehicle power supply system includes a power storage device, a plurality of devices including a plurality of noise generators, and a power distribution circuit connecting the power storage device and the devices. Each of the noise generators is connected to the power distribution circuit via a noise filter. The noise filter includes a first impedance element and a Y capacitor provided closer to the noise generators than the first impedance element. The first impedance element provided for each of the noise generators is an impedance element having a shape and a material that increase a first system impedance of each of the devices to be higher than a predetermined lower limit impedance at least in an amplitude modulation band.
