Abstract
Official abstract text for this publication.
An inverter for an electric vehicle is provided. The inverter for an electric vehicle, which controls an RPM of a motor for the electric vehicle, the inverter including a busbar connected to a power semiconductor module for supplying current, a current sensor measuring the current passing through the busbar, and a control board on which the current sensor is mounted, the control board controlling the motor for the electric vehicle according to a result measured by the current sensor. The busbar is disposed to vertically pass through the current sensor and control board.
First claim
Opening claim text (preview).
What is claimed is: 1. An inverter for an electric vehicle, which controls an RPM of a motor for the electric vehicle, the inverter comprising: a busbar connected to a power semiconductor module for supplying current; a current sensor measuring the current passing through the busbar; and a control board on which the current sensor is mounted, the control board controlling the motor for the electric vehicle according to a result measured by the current sensor, wherein the busbar is disposed to vertically pass through the current sensor and control board, and is disposed on an upper portion of the power semiconductor module to overlap the power semiconductor module when viewed from above, wherein the current sensor include a through hole through which the busbar vertically passes, a facing surface facing a lower surface of the control board, signal terminals protruding upward from the facing surface in a row, and fixing terminals protruding upward from a circumference of the facing surface at regular intervals and have a thickness greater than that of the signal terminals, wherein the current sensor is directly coupled to the lower surface of the control board by soldering of the signal terminals and the fixing terminals to the control board. 2. The inverter according to claim 1 , wherein the busbar comprises: a main body having a cylindrical shape; and a fixing part disposed on a lower end of the main body to protrude outward from the main body, wherein the busbar is coupled to the power semiconductor module through the fixing part. 3. The inverter according to claim 1 , wherein the busbar is formed of an aluminum material.
