The situation when voltage-source inverter is supplied with unbalanced system of voltages is investigated. This can cause problems in operation of an electric drive as voltage pulsations can arise in the DC-bus. Suitable control methods may be applied to eleiminate this effect in the active front-end rectifier. The paper particularly focuses on transitient processes that accompany operation od the drive. They can be caused by changes in controlof the drive, changes in load, or changes in the supply voltages.
