Assume that switch S2 is closed in the circuit shown in Figure 70. To
produce the maximum output from the pulse-forming network, the
resonant frequency of the pulse-forming network capacitance and Lch
should be approximately
a.
100 Hz.
b.
200 Hz.
c.
400 Hz.
d.
800 Hz.
16.
If the pulse-forming network is allowed to charge through the
DC
resonant charging choke, the network will charge to approximately
a.
15 KV and will produce an output pulse of approximately 7.5 KV.
b.
15 KV and will produce an output pulse of approximately 15 KV.
c.
30 KV and will produce an output pulse of approximately 15 KV.
d.
30 KV and will produce an output pulse of approximately 30 KV.
17.
The charging diode
is
used
in
conjunction
with
the
DC
resonant
charging choke to
a.
permit the use of more than one PRF.
b.
maintain a constant charge across the PFN from pulse to pulse.
c.
prevent the high-voltage power supply from being short circuited
when V3 conducts.
d.
allow the PFN to charge to a voltage that is approximately twice
the power supply voltage.
