  • Backup energy storage module with voltage leveling
    Patent number: 8154258
    Abstract: An energy storage module for providing backup power to electronic systems includes one or more capacitor banks, each including one or more capacitors for storing energy. The energy storage module also includes a first voltage regulator that may, during a normal mode of operation, provide a regulated direct current (DC) voltage to charge the one or more capacitors of each capacitor bank. In addition, each of the capacitor banks may include a voltage leveling circuit that may maintain a specific voltage on the capacitors. Further, the energy storage module includes an output circuit that may, during a backup mode of operation, provide an output voltage derived from an output of each of the one or more capacitor banks. The output circuit includes a control unit configured to regulate and combine the output of each of the one or more capacitor banks.
