(see figure 2)
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

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
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
