Abstract	:	4 novel class of hybrid, soft-switching DC-DC converters capable of achieving highpower-density, high efficiency and low EM1 is proposed. Its main distinguishingcharacteristics are zero-voltage-switching down to no-load with negligible penalty onconduction losses, and reduced filter requirement due to near-ideal filter waveforms.Soft-switching enables efficient operation at very high frequencies, which along with theinherently low filter requirement results in high power-density. In this thesis, the basicprinciples of operation of the hybrid converter are explained. Design procedures for thefilter components and factors affecting zero-voltage-switching are developed. Some ofthe topological variations of the basic hybrid configuration are introduced. Experimentalresults for the basic configuration as well as the extensions are presented in detail.Finally it is shown that while the proposed hybrid configuration is an attractive topologyfor many typical DC-DC conversion applications, its advantages are most striking forapplications like battery-charging where the input voltage is fairly constant and the output....-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
