3.5. Ignition Profile
Figure 3.5 shows the waveform of output voltage under Ignition condition. When power ON
with ignition function enabled, the output voltage will rise from 0V to ignition voltage within 10ms.
Then the voltage will stay on ignition voltage for 100ms and fall to 1000V for 900ms. This profile
will repeat every 1s. If the chamber is ignited within 10s, the output voltage will change to the set-
point directly. If not, the generator will latch.
The Ignition voltage can be set from 1000V to 1900V, 100V increment.

Description
Power will be constrained within
the value of setting prior to the
set point of regulation.
Current will be constrained
within the value of setting prior
to the set point of regulation.
Voltage will be constrained
within the value of setting prior
to the set point of regulation.
A voltage up to 1900 V is
adjustable for igniting the
system.
A ramp up to set point is
adjustable for a soft start
mechanism.
Monitoring if the output reaches
the setting of regulation within
the setting of period.
Monitoring if the output energy
reaches the setting of energy.
