A new sustain driver with energy recovery circuit based on low-voltage components and low-voltage power supply for AC plasma display panel

A novel sustain driver with energy recovery circuit is proposed based on low-cost and low-rating devices for plasma display panels. Since the proposed driver is designed by devices with half of voltage rating compared with the conventional Weber-type driver, it can take advantages of semiconductor devices with reduced conduction and switching losses as well as cheaper costs. Moreover, the proposed driver is supplied from half of required sustain voltage level in comparison with the conventional driver. The developed structure is configured with fewer devices than the prior approach with a cascaded Weber-type driver, which employs reduced voltage-rating components. As a result, the PDP driver presented in this paper can feature smaller size, lower cost, and high efficiency for both the sustain driver and the power supply circuit.
