“…The changeable transformer approach discussed earlier may lead to increased cost, power losses, and volume of the converter in practical applications. To address these issues, an alternative approach utilizing changeable resonant tank components can be employed [ 49 ] . This approach is comparatively cheaper and helps to reduce voltage stresses on components while requiring fewer gatedrive circuits.…”

The LLC resonant converter is a widely utilized power electronics converter, due to its numerous industrial and domestic applications. This converter offers some advantages such as soft-switching operation of all switches, high efficiency, high power density, low voltage stress, minimal electromagnetic interference (EMI) noise, input/output isolation, wide input/output voltage range, and reliable and good performance under the wide load variation ranges, as well as good light-load operation. However, this converter has certain limitations, which can be addressed to enhance its operation and efficiency. This paper provides an in-depth review and comparison of various LLC-based resonant converter configurations, focusing on their operational principles, mathematical analysis, control methods, and some practical applications including electric vehicle chargers, TV power supplies, LED drivers, photovoltaic cells, HVDC production, fuel cells, and wireless power transfer applications. By examining the strengths and weaknesses of the different LLC resonant converter designs, this study aims to contribute to the ongoing research efforts in improving the performance and efficiency of this important power electronics converter.

This work presents a review of the main topologies of switched capacitors (SCs) used in DC-DC power conversion. Initially, the basic configurations are analyzed, that is, voltage doubler, series-parallel, Dickson, Fibonacci, and ladder. Some aspects regarding the choice of semiconductors and capacitors used in the circuits are addressed, as well their impact on the converter behavior. The operation of the structures in terms of full charge, partial charge, and no charge conditions is investigated. It is worth mentioning that these aspects directly influence the converter design and performance in terms of efficiency. Since voltage regulation is an inherent difficulty with SC converters, some control methods are presented for this purpose. Finally, some practical applications and the possibility of designing DC-DC converters for higher power levels are analyzed.
