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.
