The main active element in thermoelectric cooling systems is Peltier module. Its action is based on the Peltier effect, which results in the conversion of electrical power into a temperature gradient. This article presents ...
This paper describes a study and the results obtained from the implementation of pulse control over a DC motor by means of both a conventional and an active driver for controlling the powerful MOSFET. The studied active driver ...
In the last several months, the world and the global media attention were focused exclusively toward the refugees, going from near east to the developed Central European countries. It was explained, that most of them are economical, ...
A novel manifestation of the Hall effect in conducting materials, semiconductors included, in the temperature range 77 K – 300 K has been experimentally observed. The nature of this phenomenon is the appearance of magnetically ...
Presented an alternative design provides centralized management of street lighting through wired communication between modules. This communication is based on a widespread and generally available in each locality Ethernet ...
The flyback commutation mode is usually chosen when capacitor has to be charged to certain high voltage. The power source supplies portions of energy into the field of air gap transformer that are further transferred to the ...
The main objective in this paper is to review the most widely used structural schemes of hybrid and electric vehicles and their basics blocks. The various sources of energy are consistently presented – fuel cells, batteries ...
