Abstract
In this paper, basic step-up switched dc/dc converters and its quasi structures are proposed. In dc/dc converters, the operation of the converters can be changed by changing the values of the elements and other parameters such as duty cycle, so the complete analysis of the basic step-up switched dc/dc converter (SSC) in different operating modes is presented. It is shown that, SSC has three different operating modes, which include synchronous operation of diodes (SOD), asynchronous operation of diodes (AOD), and boundary mode (BM). These operating modes are related to the diodes ON and OFF time. Critical inductors are calculated in BM and their values are investigated under various conditions. Inductors current ripple and the output voltage ripple are also calculated. The precise power losses analysis and small signal (SS) analysis for SSC are presented. The high voltage gain quasi structures are introduced and all of the proposed structures are compared with conventional structures. Finally, in order to verify the accuracy of the claims, the experimental results are presented.
