摘要
介绍一种用于加速器粒子束校正磁铁励磁的开关电源。该电源采用PWM控制,变换器采用双晶体管正激式变换器,额定输出为15A/15V,具有0-15A连续可调,1×10^(-3)的高稳定度,纹波小,功率损耗小,多种保护功能配有计算机远控接口。
The principle and parameters of switching power supply for correct magnet in HIRFL(Heavy Ion Research Facility in Lanzhou)is introduced.Its output rating is 15A/15V.It adopted PWM control method and two-transistor forward converter,which has high stability over 1(10^(-3),low current ripple,high efficiency and reliability.
