The sparking detection circuit comprises a filtering unit, a first filtering unit, a second filtering unit, a detection unit and a control unit, wherein the filtering unit is provided with a first filtering circuit and a second filtering circuit; the input end of the first subtraction circuit is respectively connected with the output ends of the first filter circuit and the second filter circuit; the first subtraction circuit is used for outputting an ignition detection signal; the first input end of the detection unit is connected with the output end of the first subtraction circuit, and preset voltage is connected to the second input end of the detection unit. The ignition detection signal is obtained by solving the difference value of the tube voltage after the tube voltage passes through two groups of filter circuits with different filter parameters, other influence factors are not additionally introduced, and error protection is not caused; based on the preset voltage accessed by the detection unit, the ignition detection circuit is fast in dynamic response and high in anti-interference capability, the preset voltage can be flexibly configured through software, and reusability is high.

Description

technical field [0001] The invention relates to the technical field of high-voltage generators, in particular to an ignition detection circuit of a high-voltage generator and a high-voltage generator. Background technique [0002] A high-voltage generator (also called a high-voltage power supply) and a bulb are the core components of a CT system, and the high-voltage generator provides a high-voltage power supply to the bulb. The CT system has high power, long running time, and needs to rotate during work, so the tube usually adopts a metal shell, which improves its heat dissipation capacity on the one hand, and enhances its rigidity on the other hand, but also makes the tube easier to ignite. The sparking of the tube will first seriously affect the operating performance of the CT system, and secondly cause damage to the tube and high-voltage generator, directly affecting the service life. Because the bulb and the high-voltage generator are expensive and the maintenance cos...
