  One dig­i­tal power sup­ply was de­signed for RIBLL (Ra­dioac­tive Ion Beam Line in Lanzhou) cor­rec­tor mag­net at HIRFL (Heavy Ion Re­search Fa­cil­ity in Lanzhou). Adopt­ing two par­al­lel con­nected IGBT full-bridges as the power cir­cuit topol­ogy, the power sup­ply can gen­er­ate bipo­lar DC cur­rent when it runs in the fourquad­rant work­ing states, which well meets the re­quire­ments of cor­rec­tor mag­net. SOPC plat­form of Al­tera based on Nios II is cho­sen to de­sign the dig­i­tal power sup­ply reg­u­la­tor. Em­ploy­ing FPGA as the con­trol core and uti­liz­ing SOPC prin­ci­ples, the dig­i­tal reg­u­la­tor is de­signed against spe­cial re­quire­ments of ac­cel­er­a­tor power sup­ply. The test re­sults in­di­cate that per­for­mance of the power sup­ply can meet the de­sign re­quire­ments.
