Abstract
In a power source circuit including a switching circuitas a power conversion circuit for converting by a switching operation at least one of a frequency and a voltage of an alternating voltage from an alternating power sourcevia a pair of supply linesand, one supply lineincludes a fuseas an excess current protection element, and between a ground lineand one supply line, a first line bypass capacitoris connected. Between the ground lineand another supply line, a second line bypass capacitoris connected, and another supply lineincludes an inductor. With this configuration, an unbalanced state of the circuit due to the excess current protection element is reduced so as to restrain the common mode noise.
