摘要（英）：

A power semiconductor module includes a power electronics circuit and a measuring circuit for measuring a physical parameter occurring in the power electronics circuit and for providing a corresponding measurement signal. A transmission circuit is coupled to a secondary side of a transfer unit, and an evaluation circuit is coupled to the primary side and galvanically isolated from the transmission circuit by the transfer unit. The evaluation circuit supplies an AC voltage to the primary side, causing primary current to flow on the primary side, which in turn results in secondary current on the secondary side, the secondary current being supplied to the transmission circuit. The transmission circuit receives the measurement signal and modulates the secondary current in accordance with the measurement signal, which results in a modulation of the primary current. The evaluation circuit evaluates the modulation of the primary current and generates an output signal dependent thereon.
