Abstract In this work, we have addressed the bidirectional series resonant DC-DC converter which has more resonant frequency. We have also described the conditions of operation with ZV. The processes in the converter resonant tank circuit are presented on the basis of well-known analytical models and their coefficients are defined. We have conducted experiments where the theoretical results are compared ... In this work, we have addressed the bidirectional series resonant DC-DC converter which has more resonant frequency. We have also described the conditions of operation with ZV. The processes in the converter resonant tank circuit are presented on the basis of well-known analytical models and their coefficients are defined. We have conducted experiments where the theoretical results are compared with those from simulation in the environment. Read More Read Less

Abstract This paper used the resonant DC-DC converter. We then proposed the determination of the main converter quantities on the basis of a well-known analytical modelling of the resonant tank circuit processes. Finally, we have developed the control characteristics based on normalized load.... This paper used the resonant DC-DC converter.

Abstract We have detailed the three versions of a current amplifier and each of them is realized with FETs having different channel length: 90nm, 45nm and 30 nm. Besides we have tested elementary characteristics and discussed, demonstrating the major benefit of the shortening of the channel length – extension of the frequency bandwidth. Then we have analysed the possibilities of the... We have detailed the three versions of a current amplifier and each of them is realized with FETs having different channel length: 90nm, 45nm and 30 nm. Besides we have tested elementary characteristics and discussed, demonstrating the major benefit of the shortening of the channel length – extension of the frequency bandwidth. Then we have analysed the possibilities of the issues of the shorter channels length. Read More Read Less
