[0002] In the prior art, when a device receives a trigger pulse, the high-level voltage amplitude of the multi-channel output pulses sent simultaneously by the device is limited, the pulse width is fixed, and the signal delay accuracy is not high. This results in the need to add additional circuits or equipment for adjustment if one wants to conduct experiments on high-voltage pulse amplitude or wide pulse voltage width, which is cumbersome to operate. To this end, we propose a multi-channel high-voltage pulse synchronization device. Utility Model Content

[0003] The main purpose of the utility model is to provide a high voltage pulse synchronization device with multiple outputs to solve the problems raised in the background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a multi-channel high-voltage pulse synchronization device, including a field programmable gate array, a power module, a communication module, a plurality of groups of MOSFET modules, and a host computer. The field programmable gate array is used to monitor pulse input and control multi-channel pulse output. The communication module is used to connect the communication between the field programmable gate array and the host computer, convert the signals of the host computer and the signals of the field programmable gate array to each other, so that the two can communicate. The plurality of groups of MOSFET modules amplify or convert the multi-channel output pulse signals of the field programmable gate array and output them. The power module is electrically connected to the field programmable gate array, the communication module, and the plurality of groups of MOSFET modules respectively to supply power to the field programmable gate array, the communication module, and the plurality of groups of MOSFET modules.

[0005] Preferably, the field programmable gate array is a central controller for monitoring pulse input and controlling multiple pulse outputs. When the field programmable gate array receives a pulse signal input from an interface, the field programmable gate array controls the output of the pulse signal to multiple output channels.

[0006] Preferably, the field programmable gate array is provided with a register for each channel, and the register stores information on whether the channel turns on or off the output pulse, the width of the output pulse, and the delay of the output pulse.

[0007] Preferably, the field programmable gate array communicates with the host computer through the communication module to set the data in each channel register, including the information set by the user in the host computer. For example: the pulse width time is set to 100ns or 200ms, the pulse delay time is set to 10ns, etc. The host computer transmits this information to the field programmable gate array through the communication module, and the field programmable gate array stores it in the corresponding register after calculation and analysis.

[0008] Preferably, the field programmable gate array reads the pulse delay and pulse width data stored in the register of the field programmable gate array according to the program settings, and after calculation and conversion, adjusts the adjustable delay unit and adjustable pulse width time unit of the corresponding channel. When the field programmable gate array receives an input pulse signal, it can output a high-voltage pulse signal with corresponding width and corresponding delay.

[0009] Preferably, the adjustable pulse width time unit uses a field programmable gate array to obtain the host computer time information (T), and uses a configurable clock cycle (Tc) unit and a programmable time (Td) unit to output an adjustable pulse width (Tw) signal, and then drives the output high-voltage pulse signal through multiple groups of MOSFETs. The calculation formula is as follows:
