Abstract: In this paper a new topology of high step-down dc-dc converter is proposed. The proposed converter uses an interleaved structure with one phase using a traditional buck converter and the second phase uses its inverted version. By this technique a high step down voltage conversion can be achieved as compared to the traditional interleaved buck converter. Operating principle and steady ...

— The design of an efficient monolithic buck converter is presented in this paper. A low swing MOSFET gate drive technique is proposed that improves the efficiency characteristics of a DC-DC converter. A model of the parasitic impedances of a buck converter is developed. With this model, a design space is described which characterizes the integration of both active and passive devices of a buck...

This paper reports the application of the switching control method based on the controller performance assessment. The switching of the controllers are done based on the current control performances. The accepted controller has the best estimated performance of all controllers. Finally, the practically and utility of this idea are evaluated by the voltage control result of the DC-DC converters.

Current-mode control (CMC) is an extremely popular dc-dc converter loop architecture—and with good reason. Simple operation and dynamics are achieved even though two loops, a wide-bandwidth current loop lurking inside an outer voltage loop, are required. Peak, valley, average, hysteretic, constant on-time, constant offtime, and emulated current-mode are commonly used. Each technique offers plus...

The purpose of this paper is twofold. On one hand, basics on switched circuits for designing a DC-DC converter are presented and, on the other hand, power electronics definitions associated with simple electrical networks are mentioned. In the analysis of these networks, it is necessary to take into account not only converters’ non-idealities but also how to minimize power losses. Since power l...

A method for designing power line filters for SMPS is presented. The practical design work is optimized, by excluding the nonviable combinations of filter components. The designer can choose among the theoretically viable combinations, to try practical designs. The theoretical calculations are based on chain parameters. As an illustration of the method a single stage π-filter for a buck convert...

Josephson [8] predicted in 1962 that a DC tunnel current would flow between two superconductors connected by a thin insulating layer of thickness less than about 20 Å in the absence of a voltage difference, an effect now called the DC Josephson effect. The quantum-mechanical current, called the superconducting current, arises from the tunneling of Cooper pairs of electrons of opposite spin and ...

In this work, the application of numerical device simulation to the analysis of high resistivity silicon microstrip detectors is illustrated. The analysis of dc, ac and transient responses of a single-sided, dc-coupled detector has been carried out, providing results in good agreement with experimental data. In particular, transient-mode simulation has been exploited to investigate the collecti...
