Abstract

The invention relates to a novel shock wave trigger circuit, including a trigger transformer, a power transformer, a bridge rectifier, a silicon controlled rectifier, a photoelectric coupler, a resistor, a capacitor, a silicon controlled rectifier and a diode, etc. In the part, the trigger pulse signal controls the conduction of the thyristor through the photocoupler to generate a trigger high voltage. Compared with the prior art, the beneficial effect of the present invention lies in that the trigger transformer is controlled by a silicon controlled rectifier to generate a trigger high voltage, the trigger pulse is stable and reliable, there is no leakage or burst, the circuit is simple, the trigger is stable, and it is used for extracorporeal shock wave breaking stone machine.

Description

technical field [0001] The invention relates to a trigger circuit, in particular to a novel shock wave trigger circuit. Background technique [0002] The existing shock wave trigger circuit generally adopts the high-voltage package output by the TV line, the output current is small, and it is easy to leak the trigger; or the car igniter is used, the product is large in size, high in price, and its use is limited, but there is no better solution. Contents of the invention [0003] In view of this, the object of the present invention is to provide a shock wave trigger circuit to solve the deficiencies in the prior art. [0004] In order to achieve the above object, the purpose of the present invention is achieved through the following technical solutions: [0005] A shock wave trigger circuit, including a trigger transformer, a power transformer, a bridge rectifier, a thyristor, a photocoupler, a first resistor, a second resistor, a third resistor, a fourth resistor, a fift...
