In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

For quantum information processing (QIP), it is important to have a long-lived quantum memory (QM), coupled to other QMs and quantum processors (QP). However, QM and QP systems demonstrated so far suffer from many limitations, and in the near future a single platform will not have the optimal version of all the components needed for QIP. Thus, it is also important to be able to couple quantum b...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

Yields of neutron-rich isotopes produced by fast neutron induced fission of U were measured at the ISOL set-up Production d Atomes Radioactifs Riches en Neutrons. A surface ion source was used to ionize selectively elements with low ionization potentials. In order to observe also the most n-rich isotopes, the identification was achieved by a combined measurement of band c-rays and b-delayed neu...

for beneficiation of converter slag, the role of surface phenomena on slag composition was studied. this work includes some experimental data, which were measured for basic oxygen steel (bos) slag in isfahan steel plant. all data were collected on site in the plant. the results support the idea that surface activity plays a major role in converter slag formation. it was also a new finding that ...

leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. leptin and itsreceptor (ob-r) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. the goal of this study was determination of the presence of leptin receptor mrna in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...

This paper presents a 4th order CLCL resonant converter which is suitable for constant current power supply applications. This converter is designed with Immittance characteristic with two inductors and two capacitors in resonant network. A detailed analysis and design process of a 200w converter as a constant current supply have been provided and simulation results are verified with results of...
