1. A system, comprising:
an induction machine comprising a first input for receiving a three-phase voltage from a three-phase voltage source; and
a voltage unbalance compensation device (VUC) connected in parallel with the induction machine, wherein the VUC is configured to:
receive, at a second input, the three-phase voltage from the three-phase voltage source;
determine a voltage unbalance between any of the three phases of the three-phase voltage; and
output a second voltage to the second input of the induction machine, wherein the second voltage is supplemental to the three-phase voltage and compensates for the determined voltage unbalance in the three-phase voltage received at the first input from the three-phase voltage source.
