A Literature Review on High Gain dc-dc Boost Converter

Abstract

In the recent years the use of commercial sources like coal, diesel, nuclear etc have been increased. In the coming years the conventional sources may evanesce. So, now the prime concern of the engineers and researchers are shifted towards the non-conventional sources such as solar plants, fuel cells, batteries, wind power etc. But the problem in most of these sources is deliver very low and unstable voltage and such sources are not good for commercial use. So, to utilize these non-conventional sources it is required to tie the supply to grid. dc-dc converters are widely used in PV applications. Many researchers presented advancements in dc-dc converter topologies in literature. This paper presents the wide review on recent topologies of dc-dc converters.Index Terms-High gain dc-dc boost converter; high voltage gain; interleaved boost converter; magnetic coupling; switched inductor; multi-level; multistage; switched capacitor; voltage multiplier cell.

Design and Analysis of a Three-Phase Interleaved DC-DC Boost Converter with an Energy Storage System for a PV System

“…As a result, conventional boost converters were modified with various voltage booster circuits/techniques to improve their performance. Magnetic coupling, the voltage multiplier circuit, the switched inductor and voltage lift technique, the multi-stage/level, and the switched capacitor (charged pump) are some available techniques that can be used to boost the voltage further [8,9].…”

“…Thus, it can be widely used in high-power applications, DC microgrids, and regenerative, as well as bidirectional, applications. Nonetheless, this approach has limitations, such as enormous dimensions, leakage inductances, and significant voltage spikes [8,12].…”

“…Additionally, the voltage multiplier technique is appealing due to its ability to handle high voltages, structure, and integration with various other converters. However, it requires many cells for the HV application and causes more stress on components [8,13]. Moreover, switch inductors and voltage lift circuits are also used in large-gain DC-DC boost converters due to their excellent boost capability and ability to integrate with many converters.…”

“…Moreover, switch inductors and voltage lift circuits are also used in large-gain DC-DC boost converters due to their excellent boost capability and ability to integrate with many converters. Nevertheless, this is not recommended for high-power applications, and they need more passive components [8,14].…”

“…However, controlling this converter is extremely difficult and requires an external balancing circuit since they do not provide a voltage balance for the DC link [16]. Additionally, the large number of components makes this converter relatively bulky in size [8,13]. The switched capacitor/charge pump circuit is also commonly used in high-gain DC-DC applications due to its merits, such as its low cost, compactness, weightlessness, high power density, and fast response time.…”
