Research Of A Novel Low-Voltage And High-Current DC-DC Convertor

As the rapid development of power electronics technique, the switch supply havebeen advanced. It has replaced the linear steady voltage supply and because the mostextensive direct current steady voltage supply that has been applied. It's determinedby the predominant performance of switch supply. Switch supply is consisted ofAC-DC and DC-DC. Modern microprocessor and some high speed VLSI chips mustbe ran in low-voltage/high-current and their input voltage usually is 5-48V. SoDC-DC converter or VRM(Voltage Regulation Module) is necessary. In the past years,the research about low-voltage/high-current DC-DC converter is in the ascendant.To optimize the performance of low-voltage/high-current DC-DC converter, it isnecessary to enhance it's topology and control method. In the base of the doublecurrent rectifier, this paper utilize the interleaved and synchronous rectifiertechnology and can cancel the large ripple current of output inductors significantly. Italso can improved transient response and increased efficiency. I apply Pspice softwareto simulate the circuit and the results verify the validity of the proposed scheme.
