Study on topology and control method of switching power supply circuit with low voltage and high current

Based on the special requirement of microprocessors on the dynamic load response ofswitching power supply with low voltage and high current, analysis is made on the topologic structure andcontrol method of new switching power supplies in accordance with the performance requirements byfuture microprocessors. It is shown that the cross-paralleled SR-BUCK converter circuit features smalloutput wave amplitude and high equivalent effciency, and that V2 control method may dramatically im-prove the input and load response speed of the switching converters.
