The cause of the unbalance may be a failure in the network or presence of an unbalanced load in the vicinity of the affected drive. Unsymmetrical system of voltages at the input of a voltage source inverter gives rise to the pulsations in the DC link voltage when no suitable countermeasures are taken. The effect of the unbalanced voltage supply on the system has been investigated. The influence of some circuit parameters on operation of the system was also dealt with.
