Abstract
Since inductance due to wiring to a Y capacitor is large, it is necessary to arrange the Y capacitor near a bus bar, and there is no degree of freedom in arranging the Y capacitor. Directions of currents flowing through a positive electrode side wiringand a negative electrode side wiringin a multi-core cableare a directionfrom a bus bar positive electrode terminaltoward the Y capacitor positive electrode terminal, and a directionfrom a bus bar negative electrode terminaltoward the Y capacitor negative electrode terminal, respectively. On the other hand, a direction of a current flowing through a ground wiringis a directionfrom a Y capacitor ground terminaltoward a ground terminal. A magnetic flux generated by the currents flowing through the positive electrode side wiringand the negative electrode side wiringin the multi-core cableand a magnetic flux generated by the current flowing through the ground wiringin the multi-core cablecancel each other out, and the inductance can be kept small.
