The system is modelled using Matlab/Simulink 2020. Many reasons cause fluctuations in a DC supply such as loose, corroded connections, or unregulated supply. The paper proposes a solution for fluctuations in DC supply of three phase voltage source inverter using two degree of freedom controllers Feeback FB and Feedforward FF. The results show that FB only can't solve the disturbances and sudden jumps of the DC voltage. Using both controllers FB and FF solve this problem and the performance such as overshoot, rise time, peak time, and settling time parameters are improved under different load conditions for ±15% fluctuation in DC supply7202022720202222423323https://wseas.com/journals/ps/2022/a465116-758.pdf10.37394/232016.2022.17.23https://wseas.com/journals/ps/2022/a465116-758.pdf10.1109/isie.2019.8781126Author, Bowei, L., Li, P., & Ke, X.
