In this paper, all the models of PV cell, namely ideal single-diode model, single-diode Rs model, single-diode Rp model, the two-diode model, and the three-diode model, have been discussed. SPICE simulation is done to evaluate the impact of model parameters on the operation of PV cell. The effects of the parameters are discussed. The photocurrent, IL, is proportional to irradiance, and the seri...

In this paper, a simple algorithm based on a two-diode circuit model of the solar cell is proposed for calculating different parameters of PV panels. The input parameters required for this algorithm are available from datasheets of the standard PV modules. The values of series and parallel resistances, as well as the recombination factor of Diode 2, are estimated through an iterative solution p...

We investigate a modified Murali-Lakshmanan-Chua(MLC) circuit in which the Chua’s diode is replaced with a negative conductance and pair of diode as a nonlinearity. The dual nature of this circuit exhibiting the rich dynamics of both the MLC circuit and the Duffing van der Pol is also explored. The performance of the circuit is investigated by means of laboratory experiments, numerical integrat...

As solar energy costs continue to drop, the number of large-scale deployment projects increases, and the need for different analysis models for photovoltaic (PV) modules in both academia and industry rises. This paper proposes a modified equivalent-circuit model for PV modules. A PV module comprises several series-connected PV cells, to generate more electrical power, where each PV cell has an ...

The measured I –V data and the large-signal equivalent circuit of a resonant tunneling diode are exploited, through the analog behavioral modeling capabilities of Pspice, to create a Pspice compatible model for the diode. The model is used, with very few other components, in the simulation of a number of circuit applications including a sinusoidal wave generator, a frequency multiplier and thre...

This paper provides an Analog Behavioral Model (ABM) in PSpice of a tunnel diode The PSpice parameters are implemented as separate parameterized blocks constructed from SPICE (ABM) controlled sources and extracted through experiment. A tunnel diode based oscillator is also proposed and simulated using circuit analysis software. The behavior of the tunnel diode is simulated and compared to the m...

This paper investigates Ultra Wide Band (UWB) response of a self-actuated electromagnetic wave shield based on a diode grid both in frequency and time domain. The investigation is first carried out on a shield valid for an incident wave polarized at a specific direction only, then extended to a shield effective for an incident wave polarized at an arbitrary direction. In the frequency domain, t...
