A new energy recovery sustaining driver for AC PDPs with reduced sustain voltage by half

This paper proposes a new sustaining driver for AC PDPs(Plasma Display Panels) with reduced sustain voltage by half, which improves the performance of conventional circuits such as TERES(TEchnology of REciprocal Sustainer). In the TERES circuit, the sustain voltage is the half of general sustaining driver, however, there is no energy recovery circuit. In the proposed circuit, energy recovery circuit is added and zero voltage switching or zero current switching is performed in switching devices. Although the energy recovery circuit is added, the number of active switching elements is the same as that of the TERES circuit. The operations of the proposed circuit are analyzed for each mode and its validity is verified by the simulations and experimentation.
