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.
