A HIGH EFFICIENCY SINGLE STAGE FLYBACK CONVERTER FOR PLAMA DISPLAY PANEL PDP SUSTAINING POWER MODULE
A High Efficiency Single-Stage Flyback Converter for PDP Sustaining Power Module Kwang Min Yoo Dept.of Electronics and Computer Engineering Graduate School

ABSTRACT
Since AC PDP was invented atthe University ofIllinois in 1964,thePDP technology hasbeen developed remarkably and itsuccessfully entered FlatPanelDisplay(FPD)marketthanks toitsattractivemeritssuch aswideview angle,largescreen, high brightness,and thinness.PDP market-share becomes to bewiden in largesizedisplay marketbutitscostisstillhigh to compete with other FPDs,which is the most important issue left in PDP to be solved. The operation of PDP is divided into threeperiodsofsetup,addressing,and sustaining and its brightness information is defined by sustain pulse number.The sustaining power module takes charge of total power over 80% for sustaining operation. PDP power consumption is controlled by changing the total sustain number according to displayed images due to the low panel efficiency, which causes that the load current drawn by driving circuitis varying according to subfield changes and displayedimages.Consequently itisrequiredthatPDP sustain power supply should have good voltage regulations under dynamic load changes because the image qualities and discharge margins are seriously affected by the sustain voltage.To meet the requirements,one of the most widely used methods is two-stage method.Ithas cascade structure comprised of harmonic preregulator to reduce input current harmonics and DC/DC converterto regulate a outputvoltage. In this paper, a low cost PDP sustain power supply is proposed based on flyback topology. By using Boundary Conduction Mode(BCM) to control input current regulation, DCM condition can be metunderallload conditions.

Design of a 320W Telecoms DC/DC converter.
Introduction
This report describes the design of a 320W Telecoms DC/DC converter. A push-pull forward
converter running with current mode control using the LM5030 from National Semiconductor
delivers high performance and small solution size. Custom planar magnetics from Payton
have been used throughout to reduce component build height, increase efficiency and aid
cooling.
This report contains target specification, schematic, bill of materials, magnetics design
information as well as a detailed design analysis. A full set of performance measurements is
also included taken from the prototype unit shown in Figure 1. Measurements include
conversion efficiency, power stage device temperature rise, line/load regulation, start-up
behaviour, transient load response and loop gain/phase characteristic.
