The main disadvantage of a pulse-density-modulated (PDM) voltage-source series-resonant inverter (SRI) is that the amplitude of the SRI output current fluctuates. To reduce the fluctuation, this paper presents an augmented PDM control method for the SRI. The proposed augmented PDM reduces the fluctuation in the amplitude of the SRI output current and requires fewer PDM sequences compared to the irregular PDM, and also provides a more uniform pulse density difference between PDM sequences compared to the inconstant PDM.

Główną wadą falownika z rezonansem szeregowym (SRI) z modulacją gęstości impulsu (PDM) jest to, że amplituda prądu wyjściowego SRI ulega wahaniom. Aby zredukować fluktuację, w niniejszym artykule przedstawiono metodę rozszerzonej kontroli PDM dla SRI. Proponowany rozszerzony PDM zmniejsza fluktuację amplitudy prądu wyjściowego SRI i wymaga mniejszej liczby sekwencji PDM w porównaniu z nieregularnym PDM, a także zapewnia bardziej jednolitą różnicę gęstości impulsów między sekwencjami PDM w porównaniu z niestałym PDM.
