Design of Filter Circuit in High Voltage Unit of Particle Detector

To meet high stability,low ripple requirements of High Voltage Unit in Particle radiation detectors,to design a hybrid LC and RC filter circuit to reduce power supply ripple.Through the theoretical analysis,PSpice simulation and test,the results are verified.According to this design,a High Voltage Unit was made in a high-energy particle detector on a Satelite,output voltage ripple coefficient is small,met the design purposes.Test proved that this circuit design,simple,efficient,can provide a reference for this kind of circuit design.
