This installation, consisting of a field of motorized mirrors called heliostats, captures sunlight to concentrate it towards a receiver located at the top of a tall tower. This process, known as concentrated solar thermodynamic, allows for the production of clean and sustainable energy.
[pdf] The key operating mechanism of chemical solar cells is the photovoltaic effect. When sunlight strikes a solar cell, photons are absorbed by the semiconducting material. This absorption energizes electrons, freeing them from their atomic bonds and creating charges known as electron-hole pairs.
[pdf] The main working mode of a DC conversion circuit is pulse width modulation (PWM). The basic principle is to convert DC power into square waves (pulse waves) through switching tubes, and to change the voltage by adjusting the duty cycle of the square waves (the ratio of pulse width to pulse period).
[pdf] Its principle of operation is based on the alternating closure and disconnection of power electronic switching devices, thus converting the DC supply voltage into a series of pulsed voltages, which are then converted into stabilized AC power through a filter.
[pdf] These inverters use the pulse-width modification method: switching currents at high frequency, and for variable periods of time. For example, very narrow (short) pulses simulate a low voltage situation, and wide (long pulses) simulate high voltage.
[pdf] Lithium Iron batteries work based on intercalation mechanism where lithium ions move between anode and cathode during charging and discharging cycles. When the battery is charging, lithium ions flow into it from the cathode where they are stored.
