VERY HIGH FREQUENCY SWITCHING POWER SUPPLY WITH HIGHS PERFORMANCES

Abstract

In this research paper, we try to demonstrate that it is currently possible to achieve very high frequencies in the forced switch-mode power supplies (the conventional switching power supplies) without performances degradation and preserving the qualities required in the field of power supplies. This thanks to the use of the new generation of magnetic and electronic components and an appropriate design. We have made these investigations, through experimental tests performed on a prototype operating at an extremely high frequency (2,6MHz with a current which can reach 20A). The performance quantification tests have concerned mainly: the signals quality, the static behavior, the dynamic behavior, the residuals and the energetic efficiency.
