In this study, a three-phase multilevel inverter (MLI) with low total harmonic distortion (THD) was developed, and it was found to be feasible by using a switched capacitor cell. Using just a single capacitor, a single DC supply, and nine switches, it can produce nine distinct inverter levels. The suggested inverter's gain and output voltage may need to be raised as the number of SC cells in use grows. Changing the input voltage's connection to the SC from series to parallel is accomplished by reversing the direction of electric charge flowing through the capacitor. The simulation results of the proposed model prove that 9-level inverter may be achieved using a single SC. The LTspice program was used to effectively compare the proposed topology to alternative, analogous MLI topologies. The proposed design is shown to lower total harmonic distortion (THD), while simultaneously using fewer components and a less complicated controller. The proposed inverter consumes less space and costs less because it uses fewer components. There were two types of loads used in this system: an ohmic load and an inductive ohmic load.

W tym badaniu opracowano trójfazowy wielopoziomowy falownik (MLI) o niskim całkowitym zniekształceniu harmonicznym (THD), który okazał się wykonalny przy zastosowaniu przełączanego ogniwa kondensatora. Używając tylko jednego kondensatora, jednego źródła prądu stałego i dziewięciu przełączników, można wytworzyć dziewięć różnych poziomów falownika. W miarę wzrostu liczby używanych ogniw SC może zaistnieć potrzeba zwiększenia sugerowanego wzmocnienia falownika i napięcia wyjściowego. Zmiana połączenia napięcia wejściowego do SC z szeregowego na równoległe odbywa się poprzez odwrócenie kierunku ładunku elektrycznego przepływającego przez kondensator. Wyniki symulacji zaproponowanego modelu dowodzą, że przy użyciu jednego SC można uzyskać 9-poziomowy falownik. Do efektywnego porównania zaproponowanej topologii z alternatywnymi, analogicznymi topologiami MLI wykorzystano program LTspice. Wykazano, że proponowany projekt obniża całkowite zniekształcenia harmoniczne (THD), przy jednoczesnym wykorzystaniu mniejszej liczby komponentów i mniej skomplikowanego sterownika. Proponowany falownik zajmuje mniej miejsca i kosztuje mniej, ponieważ wykorzystuje mniej komponentów. W tym systemie zastosowano dwa rodzaje obciążeń: obciążenie omowe i obciążenie indukcyjne omowe
