“…The capacitor's charging voltage and current are multiplied by analog multiplier and its output is fed to a peak detector. When peak value at output of the multiplier is detected, the peak detector triggers the Sample and Hold (S&H) circuit into sample mode for 5 ls and the corresponding voltage is held (Kuai and Yuvarajan, 2006). Low frequency pulse generator described in Linear Technology LTC6991 is responsible for controlling the duration of the PV array scanning and the time interval between two successive scannings.…”

“…The PSPICE model is validated against the practical characteristics obtained using Electronic load (Yingying Kuai and S. Yuvarajan, 2006;Ramaprabha and B.L.Mathur, 2008). Parameters like diode ideality factor n, diode reverse saturation current I o , shunt and series resistances R sh and R se were tuned to match the characteristics of the PSPICE model with that obtained for realistic module and specifications supplied by the manufacturer.…”

The aim of this study is to investigate the harmful effects of partial shading of series and parallel connected Solar PV modules and compare their performance. In order to find which connection is less susceptible to partial shading effects, a PSPICE simulation model that represents 36 cells PV module under partial shaded conditions has been used to test several shading profiles and results are presented.

“…A set of resistors are connected together and are controlled by relays and switches. In [2], a simple electronic load for testing a set of PV panels using linear metal oxide field effect transistors (MOSFETs) is presented. The proposed set up under test gives the current versus voltage and power versus voltage characteristics of PV panels by quickly scanning the load.…”

“…The proposed set up under test gives the current versus voltage and power versus voltage characteristics of PV panels by quickly scanning the load. A developed system is published in [3] based on that in [2]. This system uses LABVIEW with Microcontroller unit connected to the electronic load circuit providing higher accuracy and lower tracing time.…”
