“…The use of power MOSFETs will be put forward to allow for a higher switching frequency. On the other hand, a compromise will have to be made since a higher switching frequency implies greater switching losses and the heating of the various components constitute this inverter and thus a decrease in the efficiency [9]. In our work, the PWM control strategy is used to generate the switching signals.…”

The objective of this work is to meet the variations of the electrical energy needs by modifying the conventional topology of the conversion chain, at the same time to improve the operation of the photovoltaic system. This article focuses on improving the performance and efficiency of photovoltaic systems connected to the AC grid, through the use of advanced control algorithms (Sliding Mode control SMC and Fuzzy Logic Control FLC) for the control of DC/DC and DC/AC power conditioners. The control of the DC/DC converter allows the pursuit of the maximum power point MPPT of the photovoltaic generator with a view to a better utilization of the photovoltaic generator. The inverter control system is used to inject synchronized sinusoidal output current to the power grid and to improve the quality of energy injected into the grid. The original idea of this work is based on the insertion of a DC/DC BOOST voltage regulator in the conversion chain (between the battery and the inverter) to adjust the voltage transfer of the DC bus. This technique allows the provision of AC voltage for the sufficiency of the energy required by the control according to the need of the load.

“…Kebir designed the construction of an inverter for a photovoltaic system. Buck-boost was supported by a photovoltaic panel using TL494, which generated a PWM signal for the control of two transistors to have a 311V voltage adjusted by a control loop that held a constant voltage whatever influences temperature and sunlight [15].…”

A lamp is an artificial source of light produced by channeling electric current through the filament, which then heats up and produces light. Eye health experts believe that the ideal brightness of a lamp depends on ambient light. The rule must ensure that the brightness of the lights must be equivalent to the light around because, in that way, the light from the lights and surroundings will blend, and the eyes do not need to work harder. To overcome the problem, a control system was created by implementing the pulse width modulation (PWM) technique to control the brightness of the lights manually using a visual net application. Utilization of a microcontroller as a control center in controlling the brightness level of the lamp using the type of microcontroller AVR16, by displaying the PWM value on a form, designed on the visual net. Thus, it needed to set the level of light brightness to be ideal in the desired conditions.

Energi matahari adalah salah satu pilihan energi alternatif. Energi matahari akan diubah menjadi energi listrik oleh panel suya, namun kondisi cuaca yang tidak menentu mengakibatkan adanya perubahan suhu dan intensitas cahaya, yang menyebabkan tegangan dan arus keluaran dari panel surya menjadi tidak stabil. Oleh karena itu, konverter DC-DC diperlukan sebagai pengendali keluaran panel surya. Konverter DC-DC memiliki banyak topologi, salah satunya adalah topologi Zeta dimana tegangan keluaran konverter Zeta ditingkatkan lebih dari tegangan keluaran yang dihasilkan konverter Boost. Pengendalian keluaran panel surya dilakukan menggunakan metode Maximum Power Point Tracker (MPPT) dengan algoritma Perturb and Observe (P&O) untuk mencari titik daya maksimum yang dihasilkan panel surya. Dari penggunaan konverter zeta dengan metode MPPT P&O pada panel surya didapatkan nilai titik daya maksimum pada tegangan sebesar 23,9V dengan arus adalah 1,4A dan menghasilkan daya masukan sebesar 33,46W, dimana titik daya maksimum panel surya tersebut merupakan nilai daya yang paling optimal panel surya. Dari daya masukan tersebut menghasilkan nilai daya keluaran sebesar 24W.
