The simple diode model equation can be used to derive solar cell parameters based on current density-voltage curve. This calculation has an objective study the working of ZnO nanorod/TiO2 as photoelectrode in dye-sensitized (DSC). As a function collect and transport electron inside cell, ZnO-Nr/TiO2 bilayer heterojunction works photoanode. equivalent circuit real is usually two by considering p...

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

Printed Circuit Board (PCB) of 50mm (L) x 10mm (W) x 0.8mm (H). The Printed Circuit Assembly is composed of a set of case A ATC capacitors (American Technical Ceramic, New York) allowing a 63.7 MHz tuning and a 50 Ω matching. An active decoupling circuit was also included using a PIN diode (Temex DH 80106 PIN diode) driven by the MR system during RF pulse transmission. As for the optical modali...

This paper is an investigation into the high inrush current effect that emerges during energizing of drivers different circuit types loaded by light-emitting-diode (LED) strips. Two driver were analyzed—a voltage stabilization (VS) utilizing a Zener diode, and (CS) type in form integrated (IC). Inrush waveforms calculated for various numbers LEDs. In frame study, analysis executed energized div...

A computer program has been written to investigate the design tradeoffs of high frequency diode frequency multipliers. Velocity saturation and breakdown have been included in a device model that is part of a nonlinear multiple reflection simulation. The device doping, epitaxial layer length and velocity vs. electric field curve are input parameters. The program has a search routine to match the...

Finding the equivalent circuit parameters for photovoltaic (PV) cells is crucial as they are used in modeling and analysis of PV arrays. made silicon. These materials have a nonlinear characteristic. This distorts sinusoidal waveform current voltage. As result, harmonic components formed system. The cell smallest building block system produces voltages between 0.5 V 0.7 V. It serves source curr...
