A study of a simple PDP driver architecture using the transformer network

Abstract

In this paper, a cost-effective PDP driving circuit using the transformer network is proposed. Compared with the previous works, the half-bridge type energy recovery circuit recovers the reactive energy not to the capacitor but to the source. A single sustain board architecture removes the blocking switches which are placed on the discharge path in parallel, thus reducing the number of devices. A simple reset circuit generates the same waveform as the previous approaches. The circuit configuration and modified driving waveforms are compared with the previous works. The validity of the proposed simplified driver is verified through tests using a 6-inch panel.
