High-Voltage Pulse Generator, HV, Tesla, Wimshurst, Jacobs ...

Duty, or "dwell" is a few milliseconds, and the high-voltage pulse is generated at the end of the period when the circuit is broken and the field of T1 rapidly collapses trough the winding. An unconventional multivibrator circuit was developed to provide high saturation currents over a wide range of supply voltages.

High Voltage Pulse Transformers - Pearson Electronics

Voltage dividers and pulse-current transformers should be used on the load to be certain that the load resistance is correct at full operating voltage. Dummy loads whose resistances vary with temperature should be watched. A mismatch on the high side for the load can allow the transformer voltage to be too high even though the charging voltage is an appropriate value.

What is a High-Voltage Pulse Generator?

2021-02-06  A high-voltage pulse generator generally refers to a device that can produce voltage levels in at least the high hundreds or low thousands.

There ARE high voltage optocouplers, but if you can't get one DEFINITELY hotter than 10kV, make one: Take a PLASTIC tube, stuff one end with an LED, preferably IR, and stuff the other with a photo transistor - make SURE there is at least 20mm of separation from the "hot side" to the cold. The phototransistor can be wired directly into the micro. It would still be prudent to
