| Abstract | In this paper, a current-fed asymmetric full-bridge LLCC resonant converter is proposed for the dielectric barrier discharge (DBD) applied to the surface treatment. Compared with a previous design, the asymmetric structure with no front-end buck circuit and only two reverse-voltage blocking diodes is adopted to reduce the component count and circuit complexity. Moreover, the phase-shift control of this asymmetric full-bridge circuit is employed to regulate the AC output voltage across the DBD load. The leading switches realize ZCS by monitoring the energy of the resonant tank at the very beginning of the overlapping time of the gate signals. The lagging switches achieve ZVS by adjusting the change rate of the voltage across these switches through three small auxiliary capacitors. The method of rectifier compensated first harmonic approximation (RCFHA) is utilized to derive a curve of the transformer turn ratio and equivalent inductance, which reduces the design complexity caused by the magnetic integration technique. The experimental results from a 500W prototype are provided to verify the effectiveness of the proposed converter. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
