The soft-switching technology is widely used in DC-DC converters, DC-AC inverters, and AC-DC rectifiers. Soft-switching non-isolated DC/DC converters (Buck, Boost, Buck-Boost) are the most active research area of technology, fruitful results achieved. However, there currently no comprehensive review for converters. This paper introduces topologies presents classification characteristic all kind...

Both Soft computing based controllers and sliding mode controllers have been utilized to regulate the output voltage of dc-dc converters in response to changes in the load and the input voltage. Although both control techniques possess desirable characteristics, they have disadvantages which prevent them from being applied extensively. Many researchers have proposed the combination of sliding m...

Abstract The photoelectric properties of LED are affected by driving current and ambient temperature. To solve the problem light wane caused excessive overheating, LLC resonant converter with soft switching was chosen as main topology, improving power efficiency, reducing heat driver. Firstly, soft-switching conditions analyzed, constraint equation is obtained. Then, an improved particle swarm ...
