arc length during air arc strikes, it will reduce the peak currents during ground
strikes.
c. Operate the DRSSTC using the shortest pulsewidth possible for a given arc
length. When adjusting pulsewidth, there will be a point where additional
pulsewidth will not increase arc length, but only increase apparent “thickness” of
the arc. Increase pulsewidth only up to this point for maximum reliability.
d. Operate the DRSSTC at low PRFs. Increasing PRFs increases duty cycle and
thereby increases power and heating of the switching components. For best
reliability, maintain a lower PRF.
e. Ensure the break-point on the toroid directs arcs upward and away from the
primary coil. A grounded strike target can also be positioned to ensure that output
arcs are attracted to the target and not downwards toward the primary coil.
f. Always ensure the toroid break-out point is in place. Failure to have a break-
out point in place can lead to enormous peak currents in the power circuit and can
lead to IGBT failure.
g. Always ensure a cooling fan is used and keep run times to a minimum to
reduce heat dissipation.
