Abstract: In modern technology, power conversion equipment is very important and is now used in a great variety of products. The corresponding equipment can be divided into four groups, ac-ac converters, ac-dc rectifiers, dc-dc converters, dc-ac inverters. From recent reports, the production of dc-dc converters occupies the largest percentage of the total turnover of all conversion equipment production. However, in the traditional dc-dc converters (buck, boost, Cuk, SEPIC...), the effect of parasitic elements comes into picture at high duty ratio D, so the practical value of D has an upper limit. It is difficult to operate at higher duty ratios and hence to achieve high voltage transfer gains in those traditional dc-dc converters. With the fast development of technologies, this disadvantage limits the further applications of those traditional converters in some areas that require higher voltage transfer gains such as in communication equipment, aerospace electronics, portable devices and IC chips. Therefore, an in-depth research on advanced dc-dc power conversion topologies whose voltage transfer gains are higher than traditional dc-dc converters has been firstly performed in this thesis.
