Novel shock wave trigger circuit

Abstract

The invention relates to a novel shock wave trigger circuit. The novel shock wave trigger circuit comprises a trigger transformer, a power transformer, a bridge rectifier, a silicon controlled rectifier, a photoelectric coupler, a resistor, a capacitor, a silicon controlled rectifier, a diode and the like, wherein the photoelectric coupler isolates a trigger signal from a post-stage high-voltage part, and a trigger pulse signal controls the silicon controlled rectifier to be conducted through the photoelectric coupler, so that trigger high voltage is generated. Compared with the prior art, the novel shock wave trigger circuit has the beneficial effects that the silicon controlled rectifier is adopted for controlling the trigger transformer, then trigger high voltage is generated, the trigger pulse is stable and reliable, no trigger leakage occurs, no continuous trigger occurs, a circuit is simple, the trigger is stable, and the novel shock wave trigger circuit is used for an in-vitro shock wave lithotripter.
