Abstract
A rectifying circuit having a pair of input terminals at which voltage having an AC waveform appears, a plurality of first rectifying elements a plurality of second rectifying elements a first wiring pattern for connecting one of the paired input terminals to the plurality of first rectifying elements and a second wiring pattern for connecting the other of the paired input terminals to the plurality of second rectifying elements In the rectifying circuit, the plurality of first rectifying elements and the plurality of second rectifying elements are laid out so that at least two boundaries between the first and second rectifying elements adjacent to each other are present. With such a layout of the rectifying elements, current flow paths between one of the input terminals and the plurality of first rectifying elements and current flow paths between the other of the input terminals and the plurality of second rectifying elements are closely disposed. Therefore, AC resistance Rac in the first wiring pattern and the second wiring pattern is effectively reduced.
