Abstract: The invention relates to an insulation fault detection device (40) for detecting insulations faults in an electrical power supply system (10, 20, 30) of an electrically or hybrid driven aircraft (100), wherein the electrical power supply system (10, 20, 30) being configured with a DC section and an AC section, wherein the insulation fault detection device (40) includes: an input terminal (DC? , G) configured to receive a measurement signal (VDC?-G) from a sensor, preferably external to the insulation fault detection device (40); an output terminal (S) arranged to provide a signal for indicating an insulation fault; a processing unit (41-43) connected to the input (DC? , G) and output terminal (S) and configured to determine signal properties of the measurement signal (VDC?-G), in which the processing unit (41-43) is configured to set the signal at the output terminal(S) depending on a frequency and/or a slope of an AC component comprised in the measurement signal.

Abstract: A power supply system can include an electrical power source and a power converter connectable to a load. The electrical power source can provide a first DC voltage with a first potential difference (VH) between a first DC potential output and a second DC potential output, and a third DC potential output having a potential between the potential at the first DC potential output and the potential at the second DC potential output. The power converter can provide a second voltage with a second potential difference (VL) between a first potential output (V+) and a second potential output (V?). The second potential difference (VL) can be less than the first potential difference (VH). The power converter can electrically isolate the first DC voltage from the second voltage, and the second potential output (V?) can be connected to the third DC potential output using a first connection including an impedance.
