RECTIFIER CIRCUIT ASSEMBLY FOR REDUCING ELECTROMAGNETIC WAVE

摘要

PURPOSE: A rectifier circuit assembly is provided to attenuate an electromagnetic wave by making an electric potential between DC power output terminals with reference to a 0V output terminal of DC power to be identical to an electric potential between DC power output terminals with reference to a ground potential. CONSTITUTION: A rectifier circuit assembly for reducing an electromagnetic wave includes a rectifier circuit(100) for converting AC power into DC power. A ground potential determining/coupling part(200) is disposed between AC power input from the rectifier circuit(100) and DC power output from the rectifier circuit(100). When a ground potential power line is present in power lines of the AC power, a terminal of the DC power is coupled to the ground potential power line. When the ground potential power line is not present, the terminal of the DC power is coupled to an imaginary ground potential point.
