Trigger signal demands
Notes:
A:
Exceeding 0.2 V during pulse pause will cause a non proper turning off and
thermal damage.
B:
If the trigger altitude is below 4.5 V the device will not turn on properly and can
not carry the full current. Exceeding 5.2 V can damage the power stage and will
yield in µs-trailing after turn off.
C:
To achieve best rise times the rise time of the trigger must be as short as possible.
Shortest pulse durations are guaranteed with rise times below 200 ps. There is no
“Schmitt-Trigger” inside the LDP-V 03-100.
Trigger Output Monitor
The trigger output signal is generated with an integrated, isolated Rogowski coil and
provides an ultra fast galvanically isolated signal. The signal shape is proportional to the
derivative of the load current. It can be used for a current response triggering signal and
has no delay to the load current. Combined with an integrator it is possible to use this
signal for a galvanically isolated current monitor. The isolation barrier is suitable for
voltages up to 100 V and prevents unwanted ground loops.
Signal of the Rogowski coil:
"True" load current
Positive edge at pulse begin
Negative edge at pulse end
