Abstract :
A resonant energy-recovery circuit for a plasma display panel (PDP) employing a gas-discharge current compensation method is proposed. Its main concept is to make the resonant circuit biased by V/sub s/ and 0V instead of V/sub s//2 in charging and discharging the PDP, respectively. This operation helps the PDP to be fully charged and discharged and all main switches turned on under zero-voltage switching. Moreover, since the inductor current can compensate the large gas-discharge current, the current stresses on main power switches can be considerably reduced and all main switches have the turn-on timing margin, which ensures the no voltage drop across the PDP. Therefore, all these features could favorably provide a high energy-recovery capability, more accumulated wall charge, reduced sustaining voltage, and low electromagnetic interference. Therefore, the proposed circuit is expected to be well suited for a hang-on-the-wall PDP TV.
