A line commutated inverter transfer energy into 450 V, 50 Hz, 3 phase supply from a battery of 600 V. The battery is linked to converter through a large choke filter having a resistor ‘R’. It is desired to transfer some power into supply. Consider the firing angle ‘α’ 120° and dc load current is 7 A. Calculate the resistor ‘R’ in ohms ______
