Key-technique analysis of power source with CSRe diploes

Diploes power supply of CSRe is a high-powered stabilized pulse current source with high-speed and high-precision thyristors.The rectification technique used in this power source with an improved thyristor,technique of shunt active filter composed of IGBT,and technique of PI regulator with nested double-loops were analyzed.At the same time,the waveform acquired in debugging process was given.The stability and current ripple of power supply were processed.After continual improvements during debugging,the design requirements were met to employ this CSRe dipole power source in the cooling storage ring of Lanzhou heavy ion accelerator.
