A new dual sustaining driver using two different energy recovery circuits (ERCs) for large-sized plasma display panels (PDPs) is proposed. The proposed sustaining driver has two H-bridge inverters to be used in splitting a panel into two. Two ERCs are employed to compensate energy for charging or discharging the panel. When PDPs with the two divided panels are driven by the proposed driver, there are good uniformity in gas discharge and reduction of power consumption by the two different ERCs used in charging and discharging the panel. As results, the proposed sustaining driver has low conduction loss, diminished switching loss of all main power switches, and decrease of reactive power consumption for recovering energy. Moreover, production cost can be reduced because of the simplified ERC for discharging the panel and no additional driving circuits. To verify the operation of the proposed circuit, experimental results will be shown by using a 42-in panel.
