A Comparative Study of High-gain Cascaded DC-DC Converter Topologies
Abstract
DC-DC boost converters are utilized to step-up the voltage level to match a certain application requirement. Although Conventional boost converter is simple and easy to be implemented, it has a low boosting capability and low power density. Hence, it cannot be used for various applications where high voltage gain is required. Recently, several researches were conducted to develop new voltage boosting techniques for high gain Converters to be used for different applications. Various approaches were developed to achieve this goal, including cascaded, multilevel, interleaved, voltage lift, voltage multiplier, and many other techniques. In this paper, a comprehensive comparative study of high gain cascaded DC-DC converters is presented to categorize them based on their characteristics. Two main categories are considered for such converters, which are the quadratic boost, and hybrid boost DC-DC converter. The advantages and disadvantages of such converters are discussed in detail. These high gain converters are used extensively in high power applications when high voltage conversion ratio is required.
