A fully controlled three phase bridge is operating in inverting mode from an ac supply of 220 V, 50 Hz. The source inductance per phase is 0.32 mH. If the converter is operating with an angle of firing advance of 30°, calculate the maximum current that can be commuted, allowing a recovery angle (or) overlapping angle of 5°.
