Abstract
Radiated noise caused by switching noise of power semiconductor elements in an electrical converter is reduced. The electrical converter is characterized in comprising: a case; a power module mounted on the case and comprising a plurality of power semiconductor elements; a metal plate mounted to the power module and fixed to the case; a control circuit board arranged on the metal plate, for controlling the power semiconductor elements; and a direct-current input terminal electrically connected to a battery. The electrical converter is also characterized in being provided at the bottom with a transmission or motor, and at the top with a connector for connecting the battery and the direct-current input terminal. The electrical converter is further characterized in that the metal plate is curved, and a portion of the curved metal plate is arranged in the space between the control circuit board and the direct-current input terminal.
