Abstract: Disclosed herein are generators that are, for example, separated from the power grid during the operation, can be connected with the grid again without concerns or additional precaution measures. For example, apparatus connectors pulled out during operation can be plugged into the apparatus again or power switches actuated during the operation can be switched on again. The control device can then access data and measurements and settings that have been stored during the organized shutdown operation.

Abstract: A generator suitable for the pulsed operation comprises a power factor correction circuit having an integrated circuit. The voltage detector input of the control circuit is upstream of and connected to an amplifier. The amplifier may be configured so that its amplification factor has a value of 1 in a first condition and takes a value larger than 1 in a second condition. Moreover, the amplification may be set to a value of larger than 1 only if the voltage at the converter output is inside a tolerance range that is provided for the usual operation of the power factor correction circuit. Outside of this tolerance range, the amplification of the amplifier is then exactly 1. In doing so, the usual operation of the integrated control circuit is not disturbed, particularly during start-up.
