A 200 kV high voltage DC power supply with high stability and low ripple

The high-voltage DC power supply is widely used in scientific experiments and industrial production. To meet the requirements of high stability and low ripple of high voltage power for EBIT, the paper focuses on a designing a high-voltage DC power supply. The main circuits make use of the high frequency inversion circuit, duple voltage rectifying circuit and voltage and current dual-loop control to get the high DC voltage. The experimental results show that the DC high voltage power has good stability, small ripple, high reliability, system security, and it meets the test requirements.
