Power Semiconductor Module Comprising a Power Electronics Circuit and an Arrangement for Measuring and Transferring Measurement Data

A power semiconductor module, comprising:

• a power electronics circuit;
• a measuring circuit designed to measure at least one physical parameter occurring in the power electronics circuit and to provide a measurement signal which represents the measured parameter;
• a transfer unit with a primary side and a secondary side;
• a transmission circuit coupled to the secondary side;
• and
• an evaluation circuit coupled to the primary side and galvanically isolated from the transmission circuit by the transfer unit,
• wherein the evaluation circuit is designed to supply an AC voltage to the primary side of the transfer unit, as a result of which a corresponding primary current flows on the primary side, which results in a secondary current on the secondary side of the transfer unit, the secondary current being supplied to the transmission circuit;
• wherein the transmission circuit is designed to receive the measurement signal from the measuring circuit and modulate the secondary current in accordance with the measurement signal, which results in a corresponding modulation of the primary current,
• wherein the evaluation circuit is further designed to evaluate the modulation of the primary current and to generate an output signal dependent on the evaluation.
