A new single-stage single-switch isolated AC–DC PFC topology with high duty cycle and low current stress and high efficiency

Study on transient characteristics of secondary arc of AC/DC hybrid transmission lines on the same tower

“…In order to meet the national optimal allocation of resources, reasonably distributed electric energy [1,2], and realized large-scale transmission of electricity from the north to the south, from the west to the east, water and fire, and national networking [3], the long-distance and large-capacity power transmission mode has became the development direction of the optimal allocation of resources in China, and the advantages of high-voltage transmission lines are increasingly obvioused [4,5]. Today, highvoltage AC and DC transmission lines are complemented and supported each other, promoted the construction of a strong power grid, and promoted the rational allocation of resources and the optimization of energy structure [6,7].…”

Single Stage Long Lifespan LED Driver using Resonant Converter

“…Small size elements can dissipate power easily and improves the life of the lamp. These circuits are implemented using load resonant converters to produce the required voltage for the lamp [15]- [16], [31]- [33].…”
