A novel energy-recovery sustaining driver for plasma display panel

A novel energy-recovery driver is proposed to drive a plasma display panel (PDP) in the sustaining operation. The proposed circuit uses the parallel resonance between the inductor and the intrinsic capacitance of PDP to mainly recover the energy lost by the capacitive displacement current of the PDP. The parasitic resonance caused by the parasitic inductance and the stray capacitance is prevented greatly. A 34-in AC PDP equipped with the proposed driving circuit, operated at 100 kHz, is investigated. In addition, some prior work is shown in this paper for comparison, in which the power consumption of driving the same 34-in panel is measured. The experimental results show that the proposed driver has a low-cost structure and better performance than the prior ones.

A novel AC-PDP sustain driver based on dual resonance in sustaining mode operation

A novel sustain driver employing an energy recovery faculty is proposed for efficient driving of a plasma display panel (PDP) in the sustaining mode operation. The proposed driver uses dual resonance. One is a main resonance between an inductor and an external capacitor to produce alternative pulses and the other is a subresonance between an inductor and a panel to recover the energy consumption by the capacitive displacement current of the PDP. The operational principle and design procedure of the proposed circuit are presented with theoretical analysis. The validity of the proposed sustain driver is verified through the simulated and experimental results based on a 7.5-in diagonal panel with 200-kHz operating frequency.     

Resonant pole inverter to drive the data electrodes of AC plasma display panel

This paper proposes the use of a resonant pole inverter (RPI) as the control circuit to drive the data electrodes of an ac plasma display panel (PDP). This new application of RPI simplifies the circuit design by using fewer components, and has lower power losses than conventional driver circuits. The circuit employs two resonant MOSFETs and zero-voltage-switching technique to generate an asymmetric pulse train with moderate rising and falling time to drive the data electrodes of a PDP. The circuit also recovers the reactive energy from the PDP, like conventional energy recovery circuits. Power losses are further reduced by adding a dc offset voltage to the pulse train. The power consumptions of different driving circuits are assessed. The proposed circuit is tested on a dual-scan 42-in SVGA ac plasma display panel and is found to be practical.

A resonant energy-recovery circuit for plasma display panel employing gas-discharge current compensation method

A resonant energy-recovery circuit for a plasma display panel (PDP) employing a gas-discharge current compensation method is proposed. Its main concept is to make the resonant circuit biased by V/sub s/ and 0V instead of V/sub s//2 in charging and discharging the PDP, respectively. This operation helps the PDP to be fully charged and discharged and all main switches turned on under zero-voltage switching. Moreover, since the inductor current can compensate the large gas-discharge current, the current stresses on main power switches can be considerably reduced and all main switches have the turn-on timing margin, which ensures the no voltage drop across the PDP. Therefore, all these features could favorably provide a high energy-recovery capability, more accumulated wall charge, reduced sustaining voltage, and low electromagnetic interference. Therefore, the proposed circuit is expected to be well suited for a hang-on-the-wall PDP TV.

IGBT-Based Cost-Effective Energy-Recovery Circuit for Plasma Display Panel

A new insulated-gate-bipolar-transistor (IGBT)-based cost-effective energy-recovery circuit (ERC) for a plasma display panel (PDP) is proposed. Since it is composed of two small resonant inductors and four power diodes instead of the conventional large auxiliary circuit, it features a simpler structure, less mass, fewer power devices, higher efficiency, and lower cost. Since all its power switches are turned off under the zero-current switching operation, IGBTs can be employed as power switches. Moreover, the very stable and uniform light emitted from a PDP proves the high quality of screen. Therefore, it is well suitable for the consumer-affordable hang-on-the-wall TVs which have the desirable features such as thinness, lightness, high efficiency, low price, etc. To confirm the validity of the proposed ERC, a comparative analysis and experimental results based on a whole ac PDP driver equipped with the proposed circuit for the 42-in PDP are presented     

High-Performance and Low-Cost Single-Switch Current-Fed Energy Recovery Circuit for ac Plasma Display Panel

A high-performance and low-cost single-switch current-fed energy recovery circuit (ERC) for an alternating current (ac) plasma display panel (PDF) is proposed. Since it is composed of only one power switch compared with the conventional circuit consisting of four power switches and two large energy recovery capacitors, it features a much simpler structure and lower cost. Furthermore, since all power switches can be switched under soft-switching operation, the proposed circuit has desirable merits such as an increased reliability, and low switching loss. Especially, there are no serious voltage notches across the PDP with the aid of gas discharge current compensation, which can greatly reduce the current stress of all inverter switches, and provide those switches with the turn on timing margin. To confirm the validity of the proposed circuit, its operation and performance were verified on a prototype for 7-in test PDP.
