Reverse Biased SOA
In order to saturate the power switch and reduce
conduction losses, adequate direct base current
I
B1
has to be provided for the lowest gain h
FE
at
100
o
C (line scan phase). On the other hand,
negative base current I
B2
must be provided the
transistor to turn off (retrace phase).
Most of the dissipation, especially in the
deflection application, occurs at switch-off so it is
essential to determine the value of I
B2
which
minimizes power losses, fall time t
f
and,
consequently, T
j
. A new set of curves have been
defined to give total power losses, t
s
and t
f
as a
function of I
B1
at 64 KHz scanning frequencies for
choosing the optimum negative drive. The test
circuit is illustrated in figure 1.
The values of L and C are calculated from the
following equations:
