Regenerative power electronics driver for plasma display panel insustain-mode operation

A regenerative power electronic circuit is proposed to drive a plasma display panel (PDP) in sustain-mode operation. This driver utilizes inductors to resonate with the equivalent intrinsic capacitance of the PDP to avoid the abrupt charging/discharging operation. The energy losses due to conventional hardswitching driving and the displacement current of the PDP are mainly recovered. Compared with prior approaches, this driving circuit has a quite simple structure and is suitable for asymmetrical operation     

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.     

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

In addition, an 8-in AC PDP equipped with the proposed driving circuit, operating at 100 kHz, is investigated. With the discharge current compensation, the experimental results show that the proposed driver can maintain the AC PDP to light at lower voltage (129 V)

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.

The current injection method for AC plasma display panel (PDP) sustainer

A new concept of energy recovery for a plasma display panel (PDP) is proposed. Different from conventional LC resonant sustaining drivers, the current built up before inverting the polarity of the panel electrodes is utilized to change the panel polarity together with energy previously charged in panel capacitance. This operation provides zero-voltage switching of switches and reduction of electromagnetic interference by rejecting the surge current when the sustain switches are turned on. The buildup current helps to reduce the transition time of the panel polarity and may produce more stable light waveforms. This method is suitable for a PDP sustaining driver requiring stable light emission characteristic while it maintains low circuit loss like the series-resonant-type energy recovery circuit which is known to be a very effective method.
