A Cost Effective PDP Sustainer using Two-Winding Transformer with Hybrid Operation

In this paper, a new PDP sustainer using transformer energy recovery networks is proposed. The two-winding transformer gives the proposed topology several merits, such as a lower number of devices, simple gate driver, ZVS-on of the main switches, ZCS-off of the resonant switches and diodes and high energy recovery efficiency. The turns ratio realizes the voltage-applied overdriving technique as well as the current-injected overdriving technique. The hybrid driving technique using both methods is researched, which is useful for a faster transition time, hence providing higher contrast ratio and luminous efficiency. The proposed circuit is verified with simulation and experimental results of a 42-inch PDP.
