Ensuring a protection scheme in DC distribution system is more difficult to achieve against pole-to-ground faults than AC because of the absence zero crossing points and low line impedance. To complement major obstacle limiting fault current, several compositions have been proposed related mechanical switching solid-state switching. Among them, circuit breakers (SSCBs) are considered be possibl...

A new design for an ultra-low power, low phase noise differential 10 GHz LC voltage-controlled oscillator (VCO) which is biased in the subthreshold regime, is presented in the 0.18 μm CMOS process, for the first time. The designed circuit topology is an NMOS only cross-coupled LC-tank VCO which has an extra symmetric centre tapped inductor between the source ends of the cross-coupled transistor...

This paper presents implementations of a nonisolated, high voltage gain DC-DC converter. High voltage gain is achieved due to inclusion of resonance and transformer in the circuit. The performance of this converter is compared with two similar topologies namely coupled inductor-switched capacitor step-up converter and coupled inductor step-up converter. The proposed prototype is designed using ...

In this paper, we propose a methodology for analyzing the near-field coupling between two surface mount device (SMD) inductors using 3-dimensional electromagnetic (3D-EM) model. To develop 3D-EM model, first constitute equivalent circuit of SMD inductor from measured impedance and derive loss tangent parameters. Secondly, damped harmonic oscillator model is introduced to extract effective perme...

In this study, an integrate modeling and controlling of DC-DC boost converter topology is proposed. The traditional DC-DC boost converter topology has the major drawback such as the input power supply is an unregulated rectified voltage and the load on converters is affecting the effectiveness of the converter. The proposed boost converter topology is differed from the traditional boost convert...
