Investigation of a floating load buck DC-DC switching converter

A floating load buck DC-DC switching converter was analyzed, simulated, designed and prototyped. The floating load buck converter is first compared to the conventional buck converter. It was found that both the floating load buck converter and conventional buck converter exhibit similar conversion characteristics despit e the differences in the placement of their output inductors. A floating load buck converter w as designed to be used as a high-voltage off-line light-emitting diodes (LE Ds) driver using a Texas Instruments’ TPS92001 controller. Finally, the characteristics of this floating load buck converter LED driver were experimentally examined. This thesis is approved for Recommendation to the Graduate Council
