Paper includes efficiency change test results from standardized power supply depending on input voltage and efficiency tests of transformer based voltage regulator with different loads. Approximately is calculated necessary efficiency of voltage regulator to be used with power supply. THD analysis is done of output voltage signal, harmonic content has been measured as well. Brief explanation of possible...
This paper focuses on the problem of driving parallel strings of LEDs while ensuring current equalization between them. This issue is addressed in terms of proposing a small and simple linear topology that can be used on a number of series-associated LEDs, working as a constant current source for each string. Such topology employs a four-component circuit, with low dependence on transistor parameters,...
A feedback power control system includes: a multiplying unit receiving work voltage corresponding to the voltage drop in an electrical component and feedback voltage corresponding to the work current flowing through the electrical component, with outputting a measurement voltage corresponding to the power consumed by the electrical component, having a value equal to the product of the work voltage...
