“…Although the power 978-1-4244-1872-5/08/$25.00 © 2008 IEEE dissipated during sustaining period is lower than the maximum power, it is still the most ofpower driving the PDP compared with that dissipated during resetting and addressing periods. Therefore, the sustaining power module is mainly responsible for overall system efficiency [1][2][3]. In addition, when the PDP is operating on TV signals, the high efficiency is needed significantly at light load conditions.…”

A new PWM-controlled quasi-resonant converter for high efficiency PDP sustaining power module is proposed in this paper. The load regulation of the proposed converter can be achieved by controlling the ripple of the resonant voltage across the resonant capacitor with bi-directional auxiliary circuit, while the main switches are operating at the fixed duty ratio and fixed switching frequency. Hence, the waveforms of currents can be expected to be optimized from the view-points of the conduction loss. Furthermore, the proposed converter shows the good ZVS capability, simple control circuits, no high voltage ringing problem of rectifier diodes, no DC offset of the magnetizing current and low voltage stresses of power switches. In this paper, operational principles, features of the proposed converter, analysis and design considerations are presented. Experimental results demonstrate that the output voltage can be controlled well by the auxiliary circuit as PWM method.

“…Also, the three-level types of sustaining drivers proposed in [4], [7], [8] are not suitable for high frequency driver by the same reason multi-level types of the drivers have. Since the two-level types of sustaining drivers proposed in [3] and [9]- [14] can change the polarity of PDP at once, there is a possibility open to these drivers for high frequency driving. Secondly, the two-level types of sustaining drivers are classified according to the shape of current waveform in the energy recovery inductor as shown in Fig.…”

Although the continuous conduction current-fed types of two-level drivers proposed in [3], [9] have some desired features of high frequency sustaining driver, these drivers can not be directly applied to whole AC-PDP driver to display a image and have a. Voltage waveforms across PDP the severe problem that energy recovery efficiency of this driver is very low due to conduction loss of freewheeling current in the energy recovery inductor.

Plasma display panel (PDP) has a serious thermal problem, because the luminance efficiency of the conventional PDP is about 1.5 lm/W and it is less than 3~5 lm/W of cathode ray tube (CRT). Thus there is a need for improving the luminance efficiency of the PDP. There are several approaches to improve the luminance efficiency of the PDP and we adopt the driving PDP at high frequency range from 400 kHz up to over 700 kHz. Since a PDP is regarded as an equivalent inherent capacitance, many types of sustaining drivers have been proposed and widely used to recover the energy stored in the PDP. However, these circuits have some drawbacks for driving PDP at high frequency range. In this paper, we investigate the effect of the parasitic components of PDP itself and driver when the reactive energy of panel is recovered. Various drivers are classified and evaluated whether it is suitable for high frequency driver, and finally current-fed type with dc input voltage biased is proposed. This driver overcomes the effect of parasitic component in panel and driver and fully achieves ZVS of all full-bridge switches and reduces the transition time of the panel polarity. It is tested to validate the high frequency sustaining driver and the experimental results are presented.

A new high-performance and low cost single switch energy recovery display driver for an AC Plasma Display Panel (PDP) is proposed. Since It Is composed of only one auxiliary power switch, two small Inductors, and eight diodes compared with the conventional circuit consisting of four auxiliary power switches, two small inducton, eight power diodes, and two external capacitors, it features a much simpler structure and lower cost. Nevertheless, since the Root Mean-Square (RMS) value of the inductor current Is very small, it aho has very desirable advantages sucb as a low conduction loss and high efficiency. Furthermore, there are no serious voltage-drops caused by the large gas-dlscharge current with the aid of the discharge current compensation, which can also greatly reduce the current flowing through power switches and maintain the panel to light at a lower sustaining voltage. In addition, all main power switches are turned on under the Zero-Voltage Switching (ZVS) and thus, the proposed circuit has an Improved EM!, increased reliability, and high efficiency. Therefore, the proposed circuit will be well suited to the wall hanging PDP TV_ To confirm the validity of the proposed circuit, circuit operations, features, and design considerations are presented and verified experimentally on a 6-lnch PDP, SOkHz-switching frequency, and sustaining voltage 141V based prototype.
