Abstract: Operation of voltage-source inverter supplied with unbalanced system of voltages is investigated in the paper. This situation can lead to problems in operation of an electric drive as voltage pulsations can arise in the DC-bus. Suitable kontrol methods may be applied to eliminate this effect in the aktive front-end rectifier. The paper particularly focuses on transient processes that accompany operation of the drive. They can be caused by changes in control of the drive, changes in load, or changes in the supply voltages.
Keywords: DC-link voltage pulsations; pulse-width modulation; unbalanced voltage supply
