The account of a stage of switching for three phase rectifier with centre tap
Conditions: La≠0, Ld=∞, α≠0
Figure 1.33
Let's assume that a control pulse is applied to the thyristor VS2 and it is turned on, the VS1 is turned off at the same time.
Let's locate a reference mark at the moment of control pulse applying to the VS2.
Then
Figure 1.34
At
From here, we should find γ
Commutating voltage drop is
