Calculate the line voltage for 3-∅ 120° VSI if the value of DC supply is 24 V.

Calculate the line voltage for 3-∅ 120° VSI if the value of DC supply is 24 V. Correct Answer 16.97 V

The line voltage for 3-∅ 120° VSI is (VDC÷√2)=.707×24=16.97 V. In 3-phase 120° VSI each phase conducts for 120° and only three switches from different phases conduct at a single time.
