An inverter capable of supplying a balanced three-phase variable voltage/ variable frequency, its output is feeding a three-phase induction motor rated for 50 Hz and 440 V.
The stator winding resistances of the motor are negligibly small.
During the starting, the current inrush can be avoided without sacrificing the starting torque by suitably applying
A. low voltage at rated frequency
B. low voltage keeping V/F ratio constant
C. rated voltage at low frequency
D. rated voltage at rated frequency
