Saturable reactor with inductive D-C load — I

TWO MAGNETIC UNITS A and B, Figure 1, are used as saturable reactors, and the load consists of inductance L
L
and resistance R
L
. The gate current i
G
, flowing through the gate windings X1 to X2, is discontinuous and flows in rectangular pulses whose amplitude is the same as that of the load current. Thus the average value of the load current I
L
is larger than the average value of the gate current I
G
.
