“…Consequently, the first application of fuzzy control replaced a human operator [5]. Existing techniques increase the efficiency of solar panels, including the improvement of materials [6], the introduction of cooling systems [7], methods for controlling maximum power [8], and the conversion of direct current into alternating current [9]. As in the past [10], [11], and [12], many studies have been conducted to develop thermoelectric generators.…”

There are still some areas in the country that are having difficulties receiving uninterrupted electricity for medical aid like vaccines or insulin that require maintenance at certain temperatures. A combination of renewable energy for electricity and portable cooling boxes for medical aid can be a tremendous solution to this problem. In this research, the temperature inside the portable cooling box is kept at 2–16 °C by Peltier units running on solar power. The temperature sensor indicates the inside box’s temperature and the current sensor indicates how much power is being generated. Depending on the variation in solar radiation, the entire system is powered by direct solar or batteries. All data is processed by the Arduino using a fuzzy inference system (FIS). At the end of the process, the prototype project achieved its goal and thus played an important role in providing healthcare resources to marginalized stakeholders.

The use of multi-level inverter (MLI) technologies in high-power, medium-voltage energy regulation has been more popular in recent years. Despite the fact that the multilayer inverter has a lot of benefits, it has certain disadvantages in the layer of higher levels due to the enormous number of semiconductor switches that it employs in its construction. This may result in the inverter being of a huge size and costing a lot of money, as well as a significant rise in losses. As a result, the new MLI is suggested to minimize the number of switches in order to alleviate these challenges. This article describes a cascaded multilevel inverter with lower devices. The suggested cascaded multilevel inverter is intended for use in minimizing total harmonic distortion (THD), as shown in MATLAB/Simulink by the graph. Multilevel inverters benefit from the switching pattern of semiconductor switches, which may be used to improve their overall performance. This approach lowers the switching loss while simultaneously increasing the efficiency. In order to validate the suggested approach, simulations are carried out using the MATLAB/Simulink programming environment.

“…For this reason, improvements are made on the basic NPC topology to overcome this drawback by using clamping diodes to balance the converter. In the active neutral-point-clamped (ANPC) topology, the clamping diodes are replaced by transistors with antiparallel diodes for providing a controllable pathway for neutral current [14]- [18]. The structure of multilevel flying capacitor inverters suffers from several disadvantages which limit its use in practice; among these major drawbacks we can cite: the need for capacitor with sufficient value for each voltage level and need for charging circuit for each flying capacitor with complicated procedures for balancing voltage [19].…”

In this article, a three-phase multilevel neutral-point-clamped inverter with a modified t-type structure of switches is proposed. A pulse width modulation (PWM) scheme of the proposed inverter is also developed. The proposed topology of the multilevel inverter has the advantage of being simple, on the one hand since it does contain only semiconductors in reduced number (corresponding to the number of required voltage levels), and no other components such as switching or flying capacitors, and on the other hand, the control scheme is much simpler and more suitable for variable frequency and voltage control. The performances of this inverter are analyzed through simulations carried out in the MATLAB/Simulink environment on a three-phase inverter with 9 levels. In all simulations, the proposed topology is connected with R-load or RL-load without any output filter.
