Design of Low-Cost Address Energy Recovery Circuit of AC-PDP With Load-Adaptive Characteristics

A new address energy recovery (AER) circuit of ac plasma display panel (PDP) (AC-PDP) is proposed. The proposed circuit converter shows the load-adaptive characteristics, which can minimize the unnecessary power consumption of AER circuit according to the displayed image. Moreover, the proposed circuit, employing a p-channel MOSFET which does not require a complex floating gate driver, can be implemented with low cost. Based on the estimated equivalent capacitance of PDP, the proposed AER circuit is designed to implement the prototype for 50-in high-definition PDP. The load-adaptive AER operation and the address-power-saving characteristic are verified experimentally. Therefore, the proposed circuit is very suitable for the low-cost AER circuit of AC-PDP.
