A gate driver with Boot-strap chain is proposed to drive Multi-level PDP sustain switches. The proposed gate driver uses only one boot-strap capacitor and one diode per each MOSFETs switch without floating power supply. By adoption of this gate driver circuits, the size, weight and the cost of the driver board can be reduced.

본 논문에서는 PDP 구동 응용을 위한 간단한 구조의 Multi-level 유지 방전 회로를 제안한다. 제안된 회로는 기존의 Multi-level 유지 방전 회로에 비해 적은 수의 스위칭 소자로 구현할 수 있어 간단한 구조를 가진다. 또한, 기존의 Multi-level 회로와 동일한 수준의 소자 전압 및 전류 스트레스를 가지므로, 저가의 고성능의 저전압 소자를 사용할 수 있어 PDP 구동 회로의 원가 저감과 고효율 동작을 이룰 수 있을 것으로 예상한다. 제안된 회로의 동작 원리를 설명하고, 42" HD급 PDP에 실제 적용 실험을 하여 제안된 회로의 우수성을 보인다.

The proposed Multi-level PDP sustain Driver is composed of the semiconductor devices with low voltage rating compared to those used in the prior circuit proposed by L. Wether, and it has two resonant periods during the charging (rising period) and discharging (falling period) the PDP in the sustaining voltage waveforms. In accordance with the change of timing phase$(T_{r1},\;T_{i1},\;T_{r2})$, the performance characteristics of a commercial PDP module has been carried out and compared the characteristic with the 42V6, made of LG Electronics co., Experimental results show that the performance characteristics of PDP module are greatly influenced by the variation of $T_{i1}\;and\;T_{r2}$. The variation of $T_{r1}$ do not influence much on the performances of PDP. With the conditions that $T_{r1}=60ns,\;T_{i1}=120ns,\;and\;T_{r2}=350ns$, we could get the performances listed as the luminance is increased $14.6\%$, the power consumptions is decreased $5.9\%$, the panel efficiency is increased $24.2\%$, module efficiency is increased $21.2\%$, compared to those shown in the commercial PDP module (42V6). Therefore, the proposed multi-level PDP sustain driver expected to be suitable to actual PDP module application.

Proposed Multi-level PDP sustain Driver make use of element which has a low voltage rating instead of suggested method by the existing Webber and it passes through a second phase both rising and falling at sustaining voltage waveform In accordance with the change of timing phase(Tr1, Ti1, Tr2) performance comparison of a electric discharge characteristics in a PDP module has been carried out. At the conclusion of experimentation, the feature is extended by alteration of Ti1 and it has little to do with alteration of Tr1.

A three-level sustain circuit with six-switches for an ac plasma display panel (AC-PDP) drive is proposed. The proposed circuit features half the voltage stresses of sustain switches and clamp diodes and significantly reduced power losses compared with those of the conventional ones. This circuit, realizable with reduced cost of the semiconductor devices, gives a significant improvement in the power efficiency, essential for the design of a drive circuit for the AC-PDP. A comparative analysis and experimental results we presented to show the validity of the proposed sustainer circuit.

A new multi-level type energy recovery sustaining driver for AC PDP(Plasma Display Panel) is proposed in this paper. The multi-level driver has been developed to reduce the voltage stress on switching elements. Comparing the proposed driver with the conventional multi-level driver, 4 switching elements, 4 diodes, and two auxiliary capacitors are eliminated in the viewpoint of circuit structure. Moreover, the voltage stress on switching elements is more reduced and the sustain period is extended. To verify the validity of the proposed energy recovery circuit, computer simulations using PSpice program are carried out.

This paper proposes a novel multi-level energy recovery sustaining driver for AC PDP(Plasma Display Panel), which solves the problems of the conventional multi-level sustaining driver. While the conventional circuit improves the voltage md current stress of the switching elements in Weber circuit not only there are parasitic resonant currents between resonant inductors and parasitic capacitance and hard switching, but also the changing period between 0 and sustain voltage is too long. Comparing the proposed circuit with the conventional circuit, the number of components are reduced and the parasitic resonant currents in resonant inductors are eliminated Moreover the hard switching problem is solved by using CIM(Current Injection Method) and the operating frequency will be high as much as possible by removing Vs/2 sustain period. And the circuit operations of the proposed circuit are analyzed for each mode and the validity is verified by the simulations using PSpice program.

The power source of an AC-PDP fur sustainer circuit is operated in high-voltage and high frequency switching during the process required to achieve the gas discharge current to generate light in a PDP panel. Since PDP has the characteristics of a pure capacitive load, the displacement current that occurs during charge and discharge generates considerable reactive power. An auxiliary circuitry called Energy Recovery Circuit (ERC) reduces the capacitive displacement current. However, this auxiliary topology also bears high stress in its components. In this paper, a multilevel voltage wave shaping sustainer circuit with auxiliary ERC characteristics for an AC-PDP driver is proposed. A comparative analysis and experimental results are presented.
