POWER QUALITY IMPROVING DEVICE USING A COMMON MODE REACTOR

摘要

PURPOSE: A power quality improving device is provided to effectively eliminate a harmonic noise component using a reactor, thereby inexpensively improving power quality.;CONSTITUTION: A reactor(10) is interposed between an input terminal and an output terminal of a power line. A reactor is made of first and second coils(11,12) and a core(13). The first and second coils are wound on a core. The first terminal of the first coil is connected to the input terminal of a first power source line. The second terminal of the first coil is connected to the output terminal of the first power source line. The first terminal of the second coil is connected to the output terminal of a second power source line. The second terminal of the second coil is connected to the input terminal of the second power source line. A surge protecting element is connected between a power source line and the reactor.;COPYRIGHT KIPO 2011
