Document Type and Number:
WIPO Patent Application WO/2023/030345
Kind Code:
A1
Abstract:
A current peak value measurement apparatus (100), a high voltage generator (200), and a therapeutic device for vascular calcification. The current peak value measurement apparatus (100) comprises a PCB Rogowski coil (10), a sampling resistor (11), a signal amplification circuit (12), an integration and voltage retaining circuit (13) and a micro-controller (14), wherein the PCB Rogowski coil (10) is used for sensing a current signal in a line to be tested, and for obtaining a corresponding induced electromotive force; the sampling resistor (11) is connected to the PCB Rogowski coil (10); the signal amplification circuit (12) is connected to the sampling resistor (11); the integration and voltage retaining circuit (13) is connected to the signal amplification circuit (12); and the micro-controller (14) is connected to the integration and voltage retaining circuit (13), and is used for performing ADC sampling on the maximum value of a voltage signal, and for obtaining a current peak value of the current signal in the line to be tested according to ADC sampling data and preset current rating data. The apparatus (100) can realize real-time monitoring over a pulse current and accurately measure a current peak value of the pulse current, which does not affect an original high-voltage discharge loop, and the apparatus has the advantages of a high safety, a fast response speed, a stable process, a high consistency and a low cost.
