摘要： A control device (8) for an inverter (2) that feeds an electric machine (3), wherein the control device (8) is configured to provide pulse-width modulated switching signals (15) with a carrier frequency to drive switching elements (12) of the inverter (2), wherein the control device (8) is configured to determine the carrier frequency depending on operating point information that describes an operating point defined by a rotation speed and a torque of the electric machine (3) and, as the rotation speed increases and the magnitude of the torque falls, to increase the carrier frequency within an operating region (22) that extends within a rotation speed interval with a lower rotation speed limit (23) differing from zero and with an upper rotation speed limit (24) lying in a power-limiting operating region (21) or field-weakening operating region.

摘要： An electrical device for a converter has at least one capacitor having a first connection and a second connection, a first busbar and a second busbar is disclosed. A respective busbar has a greater extension along a transverse direction than along a longitudinal direction, and has a greater extension along the longitudinal direction than along a vertical direction. The respective busbar has a first surface and a second surface which are opposite one other with respect to the vertical direction. The device also has a first contact-connection device electrically conductively contact-connected to the first connection and via which the first connection is electrically conductively connected to the first busbar, and a second contact-connection device electrically conductively contact-connected to the second connection via which the second connection is electrically conductively connected to the second busbar. The busbars delimit a connection space in the vertical direction for connecting a semiconductor power unit.
