Abstract (en)
[origin: WO2021214160A1] The invention relates to an energy supply apparatus, which has a transformer with a first winding, a power switching device (110), a feedback device (300) and a voltage supply device (111) for providing a supply voltage (310) for the feedback device. The power switching device (110) is coupled to the first winding and can be switched periodically by means of a control signal (311) from the feedback device (300). The feedback device has a first switching element (321), which interrupts the control signal (311) when a switch-off signal, in particular an emergency off signal, occurs. The invention also relates to a method for switching off an energy supply apparatus.
