Design of voltage multipliers for high-voltage power supply

The voltage multiplier is an important component of high voltage power supply.In this paper it conducts the simulation tests in MATLAB environment and experimental tests to study the regularity of how the variety of stage number of semi-arm inverse symmetrical voltage multiplier and capacity can affect the performance of high voltage power supply.The experimental tests are carried out based on the simulation studies,and the performances of 30 kV,5mA high voltage power supply are also optimized.For the design of 30 kV,5 mA power supply silicon controlled rectifier(SCR) is used in the power conversion circuit.The results of the study show that in certain frequency condition optimizing the parameter of voltage multiplier has significant effect on improving the efficiency of power supply,reducing the ripple factor of output voltage and enhancing the stability of power supply,which provides the theoretical guidance for the design of high frequency and voltage power supply.
