AC-PDP Sustain Driver using Bidirectional Switches
نویسنده
چکیده
Abstract To minimize the cost and power consumption of PDP TV, a practical sustain circuit topology is presented with an address-and-display-period-separated driving scheme. The proposed sustain driver employs bidirectional switches to reduce the number of components. Operational principles and corresponding features are illustrated and compared with the conventional approach. The valuable contributions of the proposed high-performing sustainer has been proven by computer-aided simulations and experiments by using a prototype equipped with 7.5-inch diagonal panel operated at 200 kHz switching frequency.

An energy-recovery sustaining driver with discharge current compensation for AC plasma display panel
A novel driver with discharge current compensation is proposed to drive an ac plasma display panel (PDP). This proposed circuit uses resonance between the inductor and the ac PDP to avoid abrupt charging/discharging. The four switches of the full bridge are all operated with zero-voltage-switching turn-on. In addition, an 8-in ac PDP equipped with the proposed driving circuit, operating at 100 ...
