Abstract
Power supply for an inverter and method for operating power supply. Power supply includes a throttle arranged to connect an output end of the inverter to an electric power supply network; a secondary-side auxiliary winding that is arranged on the throttle to transmit an output voltage (UA) of the inverter to a secondary side of the throttle; and a comparator unit. The comparator unit compares a voltage (U) of the electric supply network with the voltage (U) of the secondary side of the throttle, to supply, depending upon a result of the comparison of the electric supply network voltage (U) to the secondary side voltage (U) of the throttle, electric power to the power supply either from the electric supply network or via the secondary-side auxiliary winding.
