Dynamic servo drive systems are characterized by fluctuating power demands and increasing
requirements for supply reliability. This paper presents a controlled electrical energy storage system and its
application in two industrial servo-drive environments. The system combines a bidirectional DC/DC converter, an
electrolytic capacitor module, and a control concept based on voltage droop curves and state-of-charge control. It
is designed for sub-millisecond response times, high transient power capability, and operation without real-time
communication. The first application addresses power-failure bridging in a high-performance injection molding
machine. The second application addresses peak-power reduction in an industrial DC grid supplying CNC
woodworking machines and robots. Optimized control for the active infeed converter and the energy storage system
enables peak-power reduction of more than 30%.
