“…We supply each LED with 280 mA in order to determine the amount of LEDs required for each family. This current value results from the 200 W LED luminary target-power of our future Buck power supply, which is limited to an output current of 1.4 A, according to a former survey work performed at the EI & ICT ENICarthage laboratory [76][77][78]. The corresponding supply output voltage is 143 V. We need to verify that this new current value does not bring any significant drift on the target spectrum.…”

We report a methodological approach for simulating luminary output radiation, which is achieved by mixing light-emitting diodes (LEDs) in order to match any plant absorption spectrum. Various recorded narrow-band LED spectra of different colors were first characterized and then fitted with a multi-Gaussian model. An optimizing procedure computed the optimal weighting of the relevant parameters so as to minimize the discrepancy between the combined spectrum and the reference target curve. The particle swarm optimization (PSO) method was applied because it is the most suitable technique for mono-objective situations. Within the useful spectral interval, the worst relative standard deviation between the optimized curve and recorded LED spectral power distribution (SPD) was 3.4%. When combining different LED types, the simulated light output showed that we could limit ourselves to selecting only five colored sources. This work will help us to design an optimized 200W laboratory luminaire with a pulse-width switched-mode power supply.

“…Moreover, by employing a sampled current compensation method, the estimation error is minimized. Employing an accurate model of different kind of energy converters is considered for different purposes such as loss minimization [34][35][36]. In [34], the efficiency comparison of the SiC-MOSFET and Si-IGBT-based converters is performed for DC-DC interleaved converters considering a range of switching frequency and output inductances.…”

In high voltage applications, sensorless voltage control techniques can reduce the cost and increase the reliability of DC-DC converters. In this paper, a sensorless voltage observer for a current fed Cockcroft-Walton voltage multiplier is designed. The first step is to derive the converter model. Since any inaccuracy in the derived model can result in a discrepancy between the observed voltage and the actual output voltage, an accurate model is derived, which incorporates the influential elements. Then, two voltage observers based on the extended Kalman filter (EKF) are designed and used to estimate the output voltage, transformer magnetizing current and inductor current for two different configurations of the high step-up DC-DC converter. Experimental and simulation results of the system show the efficiency of the observers. The proposed observers represent good precision as the main parasitic parameters are considered in the converter model.
