Increasing requirements for power supplies make it increasingly difficult to meet these requirements by using classical converter control methods. Already developed control methods are constantly being improved, while at the same time new solutions are tested. Such a solution is to use the law of conservation of energy to stabilize the output voltage of the converter (Bumblebee project). During the research on the digital version of the converter control circuit operating according to the new method, the characteristic oscillations in the steady state were observed. The article shows the causes of this undesirable phenomenon and how to eliminate it.

Rosnące wymagania stawiane układom zasilającym sprawiają, że coraz trudniej je spełnić wykorzystując klasyczne metody sterowania przetwornicami. Obecnie intensywnie poszukuje się metod udoskonalenia sterowania lub opracowywane są nowe. Takim rozwiązaniem jest wykorzystanie zasady zachowania energii do stabilizacji napięcia wyjściowego przetwornicy (projekt Bumblebee). W trakcie prac nad cyfrową wersją układu sterującego pracą przetwornicy zaobserwowano charakterystyczne oscylacje w stanie ustalonym. W artykule pokazano przyczyny tego niepożądanego zjawiska i sposób jego eliminacji.
