Optimization of Compensation Parameters for DC High-Voltage Power Supply Using PSO

The insulated core transformer type DC high-voltage power supply is widely used due to its advantages of high energy conversion efficiency, high output power, and low cost. However, the design and optimization of the compensation parameters for this type of power supply is a major challenge. Traditional design methods rely on the designer’s experience during the iterative optimization process, which can be inefficient and may not ensure optimal parameter values. In this study, a rapid optimization method for compensation parameters of high-voltage power supply based on the PSO algorithm is proposed. A FEM model and a field-circuit coupling simulation model have been established. To validate the feasibility of this method, the experiments have been verified on a prototype HUST-ICT electron accelerator. Finally, the method is applied to the optimized design of 800 kV/50 mA high-voltage power supply parameters. The results demonstrate that the method significantly reduces the design time of the high-voltage power supply from ten days to a few hours while improving the design efficiency.
