In this paper, a high voltage gain of DC-DC converter with design and simulation are proposed using coupledinductor. The proposed converter duty ratio is 0.65, so appropriate duty ratio is considering for this design of the converter. Due do more number of switches are considers for the converter circuit will make more switching power losses but in this converter using only two switches and hav...

This paper describes a consideration of the excitation circuit of a switched reluctance generator (SRG). The SRG is a doubly salient machine. It does not contain any magnets or brushes, and the phases are completely independent. The rotor is made of laminated iron and it does not have any winding. However, the conventional excitation circuit of this machine is an asymmetry half bridge converter...

Two architectures for a 1-V, 10-bit 200-kS/s successive approximation analog-to-digital converter (ADC) implemented in a standard CMOS 0.18 μm digital process are presented. A track-andhold circuit based on a novel implementation of the bootstrapped low-voltage analog CMOS switch with a novel rail-to-rail trackand-latch comparator circuit is described. A pMOS-only ladder containing a rail-to-ra...

The application of MATLAB/SIMULINK is developed for simulation and learning feedback controller design of dc–dc switching converters. With the help of its intuitive graphical user interface and some basic circuit theories, the corresponding SIMULINK models of the switching converter circuits can be easily constructed. Students can then use these models to learn and evaluate the closed-loop beha...

This paper proposes a new solar power generation system, which is composed of a DC/DC power converter and a new seven-level inverter. The DC/DC power converter integrates a DC-DC boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor se...

This paper presents and implements a single-stage high-power-factor light-emitting diode (LED) driver with coupled inductors, suitable for streetlight applications. The presented LED driver integrates an interleaved buck-boost power factor correction (PFC) converter with coupled inductors and a half-bridge-type series-resonant converter cascaded with a full-bridge rectifier into a single-stage ...

A novel topology for a soft-switching buck dc– dc converter with a coupled inductor is proposed. The soft-switching buck converter has advantages over the traditional hardswitching converters. The most significant advantage is that it offers a lower switching loss. This converter operates under a zero-current switching condition at turn on and a zero-voltage switching condition at turn off. It ...

Abstrac t-A logarithmic current-to-voltage converter for measuring DC currents in a wide dynamic range (from 1 pA to 1 mA) is described here. The converter is based on an operational amplifier circuit with a standard commercially-available LED diode used as a nonlinear feedback. A temperature compensation method requiring only one reference amplifier was used. This significantly reduces the com...
