Embodiment Construction

[0021]An embodiment of the invention will now be described with reference to the drawings. FIG. 1 is a perspective view schematically illustrating a device for removing inverter noise. The device is structured so as to ground a pair of bus bars 1A, 1B extending in parallel between a pair of capacitors 2A, 2B. The capacitors 2A, 2B are connected to the bus bars and to a grounding terminal 3 at symmetrical positions holding the pair of bus bars 1A, 1B therebetween. Because of this arrangement, the inductance component is substantially balanced up to a point grounded by the Y-capacitors 2A, 2B on the DC bus line connected to a converter circuit which is a source of noise. Besides, the impedance becomes very small in the front and rear connection lines holding the capacitors 2A, 2B therebetween. Therefore, this structure makes it possible to effectively remove high-frequency noise from the DC circuit of the inverter.

[0022]Here, the bus bars 1A, 1B are strap members with an insulating membe

Abstract

In a device for removing inverter noise, a pair of bus bars extending in parallel are grounded via a pair of capacitors. The capacitors are connected to the bus bars and to a grounding terminal at positions symmetrical to the pair of bus bars. Therefore, the inductance components are balanced from the source of noise to the grounded point, and impedance components are decreased from the two bus bars to a point grounded through the capacitors, making it possible to effectively remove high-frequency noise on the DC bus line of the inverter without requiring a large amount of space.
