Voltage-Source-Integrated Driving Waveform Amplifier With Energy Recovery Capability for Plasma Display Panel

This paper proposes a voltage-source-integrated driving waveform amplifier with energy recovery capability for plasma display panel (PDP). Different from conventional driving circuits having multiple voltage sources and power switches, the proposed circuit can generate various driving waveforms of PDP by using just the sustaining voltage source and fewer devices. Moreover, the proposed circuit can recover the reactive energy of the panel regardless of the slope of the driving waveform, which improves the power efficiency. Since the proposed circuit has the degrees of freedom in programming the waveforms, it also can compensate the driving waveforms to guarantee stable and uniform light emission of the PDP according to the operating temperature and variation of discharge characteristics of the PDP. Therefore, the proposed circuit may help bring the circuit cost down and enhance the reliability of the PDP.
