| Summary: | 博士 === 國立臺灣大學 === 電機工程學研究所 === 91 === AC plasma display is highly promising for large screen flat panel displays, and is now widespread in wall mounted display systems and televisions. This paper proposes the use of resonant pole inverter (RPI) as the control circuit to drive the data electrodes of 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 (ZVS) 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. Adding a DC offset voltage to the pulse train further reduces power losses. The power consumptions of different driving circuits are assessed. The proposed circuit is tested on a dual scan 42-inch SVGA AC plasma display panel and found advantageous in practical applications.
