PULSE-CONTROLLED INVERTER WITH A COOLED SHUNT RESISTOR, AND ELECTRICAL DRIVE SYSTEM HAVING A PULSE-CONTROLLED INVERTER WITH A COOLED SHUNT RESISTOR

摘要

The invention relates to a pulse-controlled inverter (2), having a housing (9), which contains a pulse-controlled inverter circuit, and at least one shunt resistor (7), which is arranged in a line section of the pulse-controlled inverter circuit, wherein the shunt resistor (7) is connected to an inner wall of the housing (9) so as to provide electrical insulation. The invention also relates to a drive system (10) for an electrically operated vehicle, having a DC voltage source (1), a pulse-controlled inverter (2), which is supplied with a DC voltage by the DC voltage source (1), and an electrical machine (5), which is connected to the pulse-controlled inverter (2) and is supplied with an AC voltage by the pulse-controlled inverter (2).
