This paper proposes the use of a resonant pole inverter (RPI) as the control circuit to drive the data electrodes of an ac plasma display panel (PDP). This new application of RPI simplifies the circuit design by using fewer components, and has lower power losses than conventional driver circuits. The circuit employs two resonant MOSFETs and zero-voltage-switching technique to generate an asymmetric pulse train with moderate rising and falling time to drive the data electrodes of a PDP. The circuit also recovers the reactive energy from the PDP, like conventional energy recovery circuits. Power losses are further reduced by adding a dc offset voltage to the pulse train. The power consumptions of different driving circuits are assessed. The proposed circuit is tested on a dual-scan 42-in SVGA ac plasma display panel and is found to be practical.
