Abstract: The theoretical model of the discharge circuit and the simulation analysis of Simulink are used to guide the design of Compact Torus Injector (CTI) high-voltage pulse power supply. The discharge experiments are performed on the CTI. The experimental results prove that the designed CTI high-voltage pulse power supply can generate a target current of 100 kA at a specific frequency, which guarantees the power supply requirements of the CTI molding field and acceleration field electrodes.
