In this paper, the effect of the cell-temperature on the performance of photovoltaic (PV) module is evaluated. The evaluation is based on a mathematical module (single diode equivalent circuit) and practically based on solar module tester (SMT). Solara®130W PV crystalline silicon module was used in this simulation. The SMT is able to supply a constant irradiance level (1000W/m2) or any other de...

An electronic diode is a nonlinear semiconductor circuit component that allows conduction of electrical current in one direction only. A component with similar functionality for electromagnetic waves, an electromagnetic isolator, is based on the Faraday effect of rotation of the polarization state and is also a key component in optical and microwave systems. Here we demonstrate a chiral electro...

n-CdO/p-Si heterojunction diode was fabricated using sol-gel spin coating technique which is a low cost and easily scalable method for preparing of semiconductor films. The structural and morphological properties of CdO film were investigated. The X-ray diffraction (XRD) spectra indicated that the film was of polycrystalline nature. The scanning electron microscopy (SEM) images indicate that th...

Based on circuit simulations, this paper investigates a concept for a power electronic interface circuit for MEMS electrostatic energy harvesters. Two ordinary overlapvarying transducers are first electrically configured as a symmetric voltage doublers which enables the device to self-start from an initially low bias. The harvesting system is then reconfigured to couple with a buck-boost DC-DC ...

A very simple nonlinear parallel nonautonomous LCR circuit with Chua’s diode as its only nonlinear element, exhibiting a rich variety of dynamical features, is proposed as a variant of the simplest nonlinear nonautonomous circuit introduced by Murali, Lakshmanan and Chua (MLC). By constructing a two-parameter phase diagram in the (F–ω) plane, corresponding to the forcing amplitude (F ) and freq...

Abstruct-Monolithic diode grids have been fabricated on 2-cm square gallium-arsenide wafers in a proof-of-principle test of a quasi-optical varactor millimeter wave frequency multiplier array concept. An equivalent circuit model based on a transmission-line analysis of plane wave illumination was applied to predict the array performance. The doubler experiments were performed under far-field il...

Intrinsically stretchable multilayer circuit boards are fabricated with a fast and material efficient method based on filtration. Silver nanowire conductor patterns of outstanding performance are defined by filtration through wax printed membranes and the circuit board is assembled by subsequent transfers of the nanowires onto the elastomer substrate. The method is used to fabricate a bright st...

This paper proposes a simplified equivalent circuit model that can be used in the presentation of characteristic harmonic components generated by full wave diode rectifiers. In the model, the load current is assumed to be constant as in many industrial applications. In order to obtain an accurate and exact analysis, the proposed model involves both current harmonics on AC side and voltage harmo...
