Abstract:

In order to overcome the difficulties in voltage-stabilization and current-limitation in the secondary output of the voltage-stabilization power with high current andmulti-output ,a second-side pos-tregu lator technology based on the magnet ic saturation property is proposed. According to this technology, a novel switch ing power is then designed.Simulated and experimental results indicate that the proposed voltage-stab ilization power attains an efficiency of 85% , and a stability up to 98. 5%. The application of the proposed power to the practice shows that the power is of both practicalva lue and promotional significance

Key words: high current, switching power, magnetic amplifier
