Abstract
A new high-efficient energy-recovery circuit is proposed to drive a plasma display panel (PDP) and compared with the conventional circuit. The proposed circuit uses only two inductors and no auxiliary circuit to recover the energy stored in the equivalent intrinsic capacitance of PDP. Therefore it features a simpler structure, less mass, lower cost of production, higher efficiency, and fewer power devices. The very stable and uniform light emitted from PDP proves the high quality of screen. It is suitable for wall-hanging color TVs. The proposed circuit, operating at 200kHz, is verified to be applicable on a 42-inch PDP by experimental results.
