摘　　要：研究并设计了一种新型的基于磁放大器分布式电源系统。该分布式电源系统采用高频母线形式,原边电路采用双管正激电路,电压前馈控制,后级利用磁放大器精确控制。这种电源系统具有高效、低成本、以及输出路数不受限制等优点。实验结果表明,该分布式电源系统可以得到纹波很小的各路精确电压。A new distributed power supply system which has the form of high-frequence bus was proposed, based on the magnetic amplifier（magamp）. The primary circuit has the form of double switch forward of feedforward control , the second circuit used the magnetic amplifier as the post regulator. The power supply system has the advantage of high efficiency, low cost, and flexi- ble. The experiments indicate that the voltage ripple of the new distributed power supply system is very small.
