集成耦合电感升压－反激变换器的性能研究
Research on the characteristics of integrated coupled-inductor boost-flyback converter
摘要
Abstract
Integrated boost-flyback step-up converter ( IBFC ) has the ability of high voltage gain in the case of small duty cycle , compared with traditional boost circuit , it avoids high power loss of circuit under the limit duty rati-o.On this basis , the integrated coupled -inductor boost -flyback converter ( ICBFC ) is presented in this paper , which utilized the coupled inductor instead of the power inductor of the IBFC .This paper studies the quantitative rela-tionship between parasitic parameter , boost characteristics and efficiency of ICBFC , which meanwhile explores the best design parameters in specific cases .Comparing two kinds of topologies , the advantage over IBFC of the ICBFC reduces current stresses of diode and voltage ripple of capacitors , and improves the reliability of power components at the same time by introducing the actual parasitic parameters under the condition of same voltage gain .On the basis of theoretical research , the 2 sets of 25 W laboratory prototypes verify the advantage of this topology .The theoretical a-nalysis agrees well with experimental results .关键词
