Abstract
A closed-loop control circuit for an auxiliary power supply unit includes a control loop for the closed-loop control of a voltage transformer of the auxiliary power supply unit via a controlled variable to produce a setpoint voltage, wherein the control loop includes an additional circuit that limits a change in the controlled variable in the event of provision of an external voltage of a main power supply unit at a first output for emitting voltage generated by the auxiliary power supply unit when the external voltage exceeds a setpoint voltage of the auxiliary power supply unit.
