Electrically conductive path device

摘要

There is provided an electrically conductive path device which can prevent radiation noise. An electrically conductive path device includes three bus bars electrically connecting a motor unit to an inverter unit, capacitance portions creating stray capacitance and an insulator. In terms of the electrically conductive path device, switching operation of a semiconductor switch located inside an inverter of the inverter unit creates change in voltage which is transmitted to the bus bar corresponding to a path from the inverter to the motor. At that time, the change in voltage is not transmitted further to the motor but is transmitted to the bus bar corresponding to a path from the motor to the inverter via the capacitance portion formed between the facing portions, i.e. via the stray capacitance.

1. An electrically conductive path device comprising:
three bus bars which electrically connect one object to the other object and a capacitance portion for creating stray capacitance, wherein the capacitance portion is formed between facing portions of the bus bars, and wherein the three bus bars are formed into a same shape, and are positioned so that a surface area of the facing portions and a distance between the facing portions are uniform.
