  • Publication number: 20070052680
    Abstract: There is disclosed an energy recovering circuit with boosting voltage-up and an energy efficient method using the same that are capable of boosting the voltage factor of an energy recovered from the panel to rapidly re-apply it to the panel, to thereby reduce the charging time of a panel capacitor and improve its energy recovery efficiency. An energy recovering circuit according to the present invention includes a voltage boosting circuit for boosting a voltage factor of an energy recovered from a panel and supplying the boosted energy to the panel. An energy efficient method according to the present invention includes steps of recovering an energy from a panel to a closed loop; and a controlling the closed loop in order to supplying the energy with its voltage factor boosted to the panel.

  • Patent number: 7009823
    Abstract: An energy recovery circuit wherein an energy stored in an inductor is applied to a panel to reduce a charge time and improve an energy recovery efficiency. In the energy recovery circuit, a switch, a capacitor and an inductor is provided to form a closed loop. A panel capacitor is equivalently provided at the panel. When the switch is turned on, a current component of an energy is charged in the inductor by an energy charged in the capacitor. When the switch is turned off, an inverse voltage is inducted into the inductor and a closed loop is formed by the inductor and the panel capacitor, thereby applying only an inverse voltage of the inductor to the panel capacitor.
