Title:
ANALOG AND DIGITAL HYBRID CONTROL-BASED HIGH-VOLTAGE GENERATOR AND CONTROL CIRCUIT AND METHOD THEREFOR, AND X-RAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/115816
Kind Code:
A1
Abstract:
The present application relates to the field of X-rays, and specifically to an analog and digital hybrid control-based high-voltage generator and a control circuit and method therefor, and an X-ray system, comprising: a PID analog closed-loop control module, having the input end thereof connected to the output end of a feedback circuit and a reference voltage source, and used for outputting a frequency signal on the basis of error voltage between the voltage at the output end of a trimming circuit and reference voltage generated by the reference voltage source, the reference voltage being preset tube voltage of an X-ray tube; and a control unit, having the input end thereof connected to the output end of the PID analog closed-loop control module and the output end thereof connected to the input end of a driving circuit, and used for receiving the frequency signal output by the PID analog closed-loop control module, performing frequency division processing on the frequency signal, and outputting the frequency signal subjected to frequency division to the driving circuit. The heating problem of power devices such as an inverter is effectively avoided, damage of the high-voltage generator is reduced, and performance parameters of the high-voltage generator are maintained.
