<p>The present invention relates to a power conversion unit for an electric motor vehicle. The present invention includes an upper shielding plate and a lower shielding plate for shielding noise from the outside; a bus bar connected to a high voltage connector; and an embedded type power conversion board which is arranged between the upper shielding plate and the lower shielding plate and has a power sensing circuit of sensing a current flowing along the bus bar and a power conversion circuit for converting power inputted from the outside to drive an electric motor vehicle on a printed circuit board (PCB). Accordingly, the present invention can improve the stability of a wire and the reliability of signal transmission, and contribute to the miniaturization and lightening of products because a current sensing circuit and a power conversion circuit are directly connected through an PCB conducive pattern unlike an existing method of connecting a separate current sensing board and a power conversion board through a connector.</p> |
