Еnergy-efficient power summator of alternative power sources based on step-up capacitor dc-dc converters
https://doi.org/10.15518/isjaee.2024.01.051-061
Abstract
Proposed a new principle of the energy efficient and small-sized capacitor DC-DC converters that are able to perform not only the conversion function of the output voltage of the several different output parameters of alternative DC voltage sources having a common grounded bus, but also to provide the summation of their power in a common load. Proposed the principle of multi-cycle SSCDC construction, which provides additional improvement of their mass-size characteristics under the increased power of alternative sources conditions. It is shown that the effect is achieved by a multiple increase in the conversion frequency of individual SSCDC modules and practical elimination of the large output capacitor by means of a sharp decrease and multiple increase in the first harmonic frequency of the total output current. The analytical expressions that allow to calculate the reactive elements parameters, analyze and quantify their efficiency has been obtained.
