摘要： A high-voltage generating circuit for a catheter and an ablation tool. The high-voltage generating circuit comprises: N voltage conversion units (111a, 121a, 131a, 141a), N energy storage units (112a, 122a, 132a, 142a), a voltage adjustment unit (200a), and a control unit (300a). Input ends of the N voltage conversion units (111a, 121a, 131a, 141a) are connected in parallel and then connected to a total input end, and output ends of the N voltage conversion units (111a, 121a, 131a, 141a) are connected in series and then connected to a total output end; the N energy storage units (112a, 122a, 132a, 142a) have one-to-one correspondence to the N voltage conversion units (111a, 121a, 131a, 141a); an input end of the voltage adjustment unit (200a) is connected to the output ends of the voltage conversion units (111a 121a 131a 141a) and an output end of the voltage adjustment unit (200a) is connected to the total output end; and the control unit (300a) is connected to the N voltage conversion units (111a, 121a, 131a, 141a) and the voltage adjustment unit (200a) so as to adjust the output voltage of the total output end to be a target voltage. In this way, the output voltage can be quickly switched to the target voltage by means of the multiple input-parallel output-series voltage conversion units (111a, 121a 131a, 141a), and meanwhile, the output range of the voltage is widened, such that the application prospect of a pulsed electric field ablation technology in treatment of arrhythmia is improved.
