The configuration and performance of high voltage generator(HVG) of a high power low-energy electron accelerator

designed for industrial applications

were introduced in this paper.The simulating circuit model parameters of the HVG were determined based on its basic transformer-type working principle

and then the Matlab software was used to simulate steady work condition of the HVG.Furthermore

the instant voltage distribution along the cascades of the HVG was analyzed under the malfunction of breakdown between the high voltage electrode and the ground electrode.After that

the parameters of HVG were partly adjusted according to the simulating result

and performance of the equipment was improved as a result of the adjustment.In addition

the interlayer breakdown between the sections of cascades was simulated by Matlab

and some improving methods were adopted to enhance the performance of HVG for protecting the equipment during the high voltage breakdown.
