Document Type and Number:
WIPO Patent Application WO/2018/056364
Kind Code:
A1
Abstract:
An electronic device according to the present invention is provided with: a power supply unit; and a load. The power supply unit is provided with: an input unit which receives power from an alternating current power supply; an earth terminal; a rectifying circuit; a circuit unit which is connected to a direct current output of the rectifying circuit, and supplies power to the load; a first varistor which has one end connected to one input terminal of the rectifying circuit; a second varistor which has one end connected to the other input terminal of the rectifying circuit, and has the other end connected to the other end of the first varistor; and an arrester which has one end connected to the other end of the second varistor, and has the other end connected to the earth terminal. The capacitance of each of the first varistor and the second varistor is 40% or more of the sum of the ground capacitances for the power supply unit and the load.
