Abstract:A new distributed power supply system which has the form of highfrequence 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 flexible.The experiments indicate that the voltage ripple of the new distributed power supply system is very small.
Key words: highfrequency; magamp; distributed power supply(DPS); double switch forward
