In the current context of reducing pollution through the most economical use of energy in the field of transport, it is necessary to find solutions with high efficiency for the recovery and storage of energy produced by moving vehicles in congested traffic conditions. Motor vehicles equipped with the thermal engines that equip modern cars primarily use a lead-acid battery to start the engine. The battery must provide a current of several hundred Amps for starting. Such batteries require high energy capacities, and their construction uses large amounts of Pb, an extremely polluting material. Also, the use of classic batteries in the automotive industry, in addition to pollution, is not effective either in terms of cost/weight When braking, electric cars generate large currents whose energy cannot be fully accumulated in batteries manufactured on the basis of Pb due to the limiting electrochemical process through which the electric charge accumulates. The modern computers that equip new vehicles have powerful processors that can command and supervise many phenomena on the car. A first step in this direction was made by the introduction of the Start-Stop system, which stops the engine when the vehicle is not moving or goes into the braking stage. When the accelerator pedal is pressed, the engine must start forcefully and at a higher speed than when the engine is running at “idle”. In this case, the starter is operated with a voltage 50% higher than the nominal voltage of the accumulator battery and a current of hundreds of amperes. In this case, a special passive component is used, namely the supercapacitor. A second step in the direction of reducing pollution is the considerable reduction of the battery capacity of Pb batteries, so less polluting, but which can ensure good starting even after a long time. This can be done by connecting a supercapacitor in parallel with a low-capacity Pb-based battery and an electronic control and monitoring system.

Temperature and humidity are the most important factors that must be controlled during egg incubation. The irrelevant temperature and humidity values during the incubation period often result in unwanted conditions. This paper introduces a design and implementation of an electronic control unit for an incubator. In order to achieve a high degree of hatching in the incubators, it is necessary to ensure precise maintenance of the parameters of the indoor microclimate. In this work, an electronic system for controlling the temperature and humidity of the air has been developed and investigated. For this purpose, a block diagram of the system has been developed, a basic electrical circuit of the electronic module has been built, and the individual blocks of the electronic system have been designed. Simulation and experimental results for the operation of the system have been obtained.

Nowadays, more and more emphasis is placed on non-polluting electrical charge devices that increasingly satisfy the needs of the application. For this reason, a good part of the research focuses on the use of supercapacitors as devices for storing the electric charge and at the same time generating this charge to the system that needs a power supply. The capabilities of supercapacitors can significantly contribute to the proper functioning of the system where they are embedded and can also prolong its life given the fact that they have a very large number of charge-discharge cycles (> 100,000). Like any relatively new component, which is constantly being tested, it has also some disadvantages that the researchers in this area have tried to reduce. The materials used in the realization of supercapacitors represent the main source of influence on their operation. For example, the maximum working voltage (nominal voltage) is determined by the electrolytic decomposition voltage of the electrolyte solution. Talking about this, the paper's aim was to make and test new coin cells of supercapacitors in order to increase the maximum working voltage and capacitance per cell. We propose to use new materials that seem to bring benefits from this point of view to obtain supercapacitors that work at higher working voltages (over 3V). Thus, after testing and interpreting the obtained data, we can conclude whether the materials have been chosen according, in combination between electrode material and electrolyte solution proved to be suitable in finding a solution to this disadvantage of supercapacitors.

Multilayer ceramic capacitors (MLCC) are present in every electronic device. Unfortunately, due to the dielectric material they are made of, they vibrate in the presence of an electric field. This vibration is transferred to the PCB via the solder joint creating the acoustic noise known as “singing” capacitor phenomenon. There are multiple solutions to attenuate this phenomenon. In this paper, we investigate the effect of solder paste reduction, oven curing, varnishing, MLCC orientation, and layout optimization on the acoustic noise caused by MLCCs.

A portable electronic system is an embedded electronic device that helps the consumer track a wide range of personal biometric data, ambiental data for monitoring the environment, or their fitness activity. The main benefit of data collection is that it can define your current health state and identify, treat, and manage potential medical issues that may arise. For this reason, in this paper, a portable embedded device was designed for monitoring a person's activities and environmental parameters. It was therefore necessary to create two PCBs, one for the portable device and the other for the receiver. Using the two PCBs, we successfully broadcast data up to 600 meters around the city. This distance exceeds the typical range attained using Bluetooth or Wi-Fi connected devices.

The paper presents the use of the experiential learning approach for teaching the topic “Implementation of Brent-Kung Adders Using Computer-Based Training”. Brent-Kung adders are implemented with various software tools, e.g. MS Excel, Logisim, and ISE Project Navigator, for simulating the process of adding two binary numbers. Based on the flipped classroom strategy, students investigate the theoretical issues concerning Brent-Kung adders, then they implement these adders with various computer-aided tools and in the end, they test the FPGA-based implementation of Brent-Kung adders with a lab board created at our University. The applications will be used in the educational process in the courses “Digital Electronics” and “Pulse and Digital Devices” at the University of Ruse, with the aim of easy adoption of the material studied by the students.

Conductive polymers are good candidates for artificial muscles, considered in microactuators structures with two polymer plates joined by a solid electrolyte. Dopants are essential for the actuating mechanism, considering a oxidation or a reduction process with exchange of anions / cations with the electrolyte. These processes are controlled by different parameters, like the relative diameter of the ions, the used electrolyte and the relative interaction forces solvent-ion, solvent-polymer, polymer-ions and polymer-polymer. For the two classes of dopants, the energy conversion efficiency was calculated based on the data obtained by simulation methods, using the microactuator structure reproduction, with help of the HFSS program (by Ansys). The efficiency can vary between about 20…40%, in function of molar ratios (0.1…0.4) and anions / cations ion radii. These parameters can be optimized analyzing a polyvalent evolution of the efficiency, in function of pairs of correlated parameters, which characterize the structure. Discussion is open in order to choose the practical meaning of the optimizing process, for recommending the optimal conductive polymer composition, used for actuation.

An essential issue in power electronics field is the limitation of power losses in the power supply grid. The distortions created by each consumer add up in the main network. The effect seen by customer is distorted mains voltage. The effects observed by the electric energy distribution operator consist in the increase of losses in the network (at the same active power, the supply current of the harmonic polluting consumer is higher than the supply current of the resistive consumer). For an efficient operation, the circuits used to compensate the over polluted grids need ideal reference signals. Starting from the idea of identifying a viable solution to this problem, this paper proposes a designing method and testing of a quadrature oscillator (QVCO) to provide the compensation circuit with the ideal necessary signal. The proposed circuit was designed and tested. The experimental results obtained during the QVCO testing show that the designed QVCO circuit provides a perfect reference sinusoidal signal, synchronous with the fundamental voltage of power supply network/grid.
