The basic working principle of a DC high-voltage generator is to convert AC power into DC power



and then boost the voltage to the required level through a voltage-raising circuit. The specific steps include:



Rectification: Use a rectifier to convert the input alternating current (AC) into pulsating direct current (DC).

Filtering: After smoothing through a filter, a more stable DC output is obtained.

Voltage boosting: Use a transformer or other type of voltage-raising device to further increase the voltage level, ultimately achieving the required high-voltage DC output.

To ensure the stability and accuracy of the output voltage, modern DC high-voltage generators are typically equipped with a feedback control system that monitors and adjusts output parameters in real time.
