#CMT# #/CMT# The device i.e. inverter (20), has a pilot unit (36) for performing feedthrough of pilot control, where a pilot control value is determined by the pilot unit based on a desired value of an operating parameter. A control unit (34) determines a control portion based on an actual value of the operating parameter. A combining unit forms a position value based on the pilot control value and the control portion. A set of power switches supplies electrical power to an electric machine (24) according to the position value. #CMT# : #/CMT# Independent claims are also included for the following: (1) a method for controlling an operating parameter of an electric machine (2) a powertrain for a motor vehicle. #CMT#USE : #/CMT# Power electronics device i.e. inverter, for use in a powertrain i.e. hybrid powertrain, of a motor vehicle i.e. motor car, (all claimed) to supply electrical power to an electric machine. #CMT#ADVANTAGE : #/CMT# The need of external connections between the device and the control device is avoided, so that defect-prone and lossless control or regulation of the electrical machine is obtained. The short link is provided between the pilot unit and the control panel, thus minimizing propagation delays and increasing speed of control behavior. The control device and the electric machine are connected together by short attachment, thus reducing signal running time, enhancing electromagnetic compatibility of the powertrain and reducing fault liability. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a powertrain. 10 : Powertrain 20 : Inverter 24 : Electric machine 34 : Control unit 36 : Pilot unit. |
