Power Electronics Let of a thyristor Vc1, Vc2, Vc3 are forward break over voltage for gate current Ig1, Ig2, Ig3 respectively. Then Vc1 > Vc2 > Vc3 when Ig1 < Ig2 < Ig3. Vc1 > Vc2 > Vc3 when Ig1 > Ig2 > Ig3. Vc1 > Vc2 > Vc3 when Ig1= Ig2 Vc1 = Vc2 = Vc3 any value of Ig. Vc1 > Vc2 > Vc3 when Ig1 < Ig2 < Ig3. Vc1 > Vc2 > Vc3 when Ig1 > Ig2 > Ig3. Vc1 > Vc2 > Vc3 when Ig1= Ig2 Vc1 = Vc2 = Vc3 any value of Ig. ANSWER DOWNLOAD EXAMIANS APP
