Present invention solves the technical problem that being: overcome the high chamber pressure ring of existing high back pressure plasma igniter high-voltage trigger
The deficiency that under border, reliability is low, electromagnetic interference is big, provides a kind of plasma igniter that can be used for electric discharge under high chamber pressure environment
Triggering device.
The technical scheme is that design a kind of high back pressure plasma igniter high-voltage trigger it is characterised in that
Including power supply 1, plasma square 2, isolation circuit and voltage-multiplying circuit；From the positive pole of power supply 1 to negative pole, it has been sequentially connected in series plasma square
2 and isolation circuit, the outfan of voltage-multiplying circuit is connected between ion square 2 and isolation circuit；The input of described voltage-multiplying circuit
Input any type of alternating current；Described isolation circuit is parts with unilateral conduction；Plasma square 2 exists to be put
