Abstract

A printed circuit board includes a power input terminal, a positive trunk line, a negative trunk line, a first switching circuit, a second switching circuit, a first positive wire, a second positive wire, a first capacitor, a second capacitor, and a bypass circuit. The first positive wire connecting the positive trunk line with the first switching circuit without passing through the second switching circuit. The second positive wire connecting the positive trunk line with the second switching circuit without passing through the first switching circuit. The first capacitor provided between the first positive wire and the negative trunk line. The second capacitor provided between the second positive wire and the negative trunk line. The bypass circuit connecting the first positive wire with the second positive wire.
