Original Abstract Submitted
A power electronic circuit includes a topological switch having at least two power semiconductors connected in parallel, a driver configured to drive the power semiconductors, a gate resistor between the driver and the power semiconductors, a monitoring device to detect a voltage drop between two load terminals of the topological switch and output it as a signal, and a comparison device arranged between the driver and the gate resistor and configured to compare the signal output from the monitoring device with a current signal output from the driver, wherein, in the event that the detected difference exceeds a predetermined threshold value and a signal is additionally output by the driver instructing that the power semiconductors should not be conductive, the monitoring device outputs an emergency signal to the driver, which is configured to then output a signal to the power semiconductors to put them into a safety state.
