3-phase 1800 mode VSI

In 1800 mode VSI  each thyristor  conduct  for 1800 and two  thyristor  are fired  at 600 interval. For  example  if thyristor  T1  is fired at 00 then it will conduct for 00 to 1800 and next  thyristor T2 will fine at 600 table 2.4 explains the period of  conduction and firing angle of each thyristor.
