Abstract
An uninterruptible power supply (UPS) for a three-phase alternating current network, in particular a medium-voltage network, includes an energy storage system, a switch, an LC resonant circuit, which is a series circuit of an inductance and a capacitance, and a control unit for controlling the switch. The switch and the LC resonant circuit are connected in series, and the series circuit of the switch and the LC resonant is arranged between a network feed and the energy storage system which is connected to a load. There is also described a method for operating such a UPS and a corresponding computer program.
