A three-phase full converter is driving a DC motor. If a continues current of Im amperes is flowing through the motor load, then find the rms value of supply current drawn by the converter to drive the motor.

A three-phase full converter is driving a DC motor. If a continues current of Im amperes is flowing through the motor load, then find the rms value of supply current drawn by the converter to drive the motor. Correct Answer √2Im/√3

The RMS value of the supply current IS over π radians would be (IS)2 = (1/π) x (Im)2 x (2π/3) = Im√2/√3.
