Abstract: A method for operating an inverter and an inverter configured to convert DC power supplied from a DC power source into AC power supplied to an AC network by applying operational parameter limits which define limits for allowed operating points of the inverter, collect, during the converting, data of operational conditions related to the inverter, determine on the basis of the collected data whether the set operational parameter limits can be optimized with regard to one or more optimization criteria, and in response to determining that the set operational parameter limits can be optimized, adapt one or more of the set operational parameter limits applied in the converting on the basis of the collected data.

Abstract: The present invention relates to the field of electric drive devices and arrangements comprising a plurality of power semiconductor components formed in or on a common substrate, and more particularly to an arrangement for monitoring the condition of a power semiconductor module of an electric drive device and an electric drive device. The arrangement for monitoring the condition of a power semiconductor module of an electric drive device comprises at least one pair of sensor elements, each pair comprising a first PCB copper trace sensor element and a second PCB copper trace sensor element, arranged on a printed circuit board parallel next to each other as a sensor element pair, wherein said first PCB copper trace sensor element is connected to a positive DC supply voltage source (UDC+) and said second PCB copper trace sensor element is connected to a negative DC supply voltage source (UDC−) of said electric drive device so that upon applying the DC supply voltage of said electric drive device said DC supply voltage is applied to said at least one pair of sensor elements at the same time as to the circuit components of the power semiconductor module.
