The invention relates to a high-voltage discharge technology, and provides a high-voltage discharge circuit and a high-voltage discharge circuit control method. According to the invention, the problems of large size, high power loss and long response time of the existing high-voltage discharge device are solved, and the main technical scheme is that a microcontroller module switches on an MOS transistor I after receiving a trigger signal I, and switches on an MOS transistor II after receiving a trigger signal II; then an MOS transistor III works in a high-frequency switching state, a boostingtransformer I transforms voltage and then charges a capacitor I, an MOS transistor IV is switched on to charge a capacitor II, and then a silicon controlled rectifier is switched on after a trigger signal III is received, and the voltage of the capacitor II transforms voltage through a boosting transformer II after the silicon controlled rectifier is switched on to trigger a trigger tube; and after the trigger tube is conducted, the capacitor I discharges to a post-stage circuit. According to the present invention, a high-voltage discharge device is small in size, low in power loss and shorterin response time. The circuit and the control method thereof are particularly suitable for detonator detonation, pulse lasers, weapon ignition and other devices.
Description
technical field [0001] The invention relates to high-voltage discharge technology, in particular to a high-voltage discharge circuit and a control method for the high-voltage discharge circuit. Background technique [0002] With the development of power supply technology, the high-voltage power supply discharge devices currently used in detonator detonation, pulse lasers, weapon ignition and other equipment have smaller and smaller requirements for volume, stricter requirements for logic control and judgment, and must not be used under abnormal conditions. Mis-triggering is allowed to cause discharge action. The current high-voltage discharge device is generally controlled by a PWM pulse width controller plus a logic judgment circuit, which will increase a lot of logic judgment circuits, resulting in a large volume of the high-voltage discharge device, high power loss, and long response time, and the amplitude of the trigger signal Inaccurate value judgment, unmeasurable du...
