Abstract
The traditional step-down Buck circuit has the problem of low efficiency and large ripple for the discontinuous input current. The improved step-down Cuk circuit can solve these problems. The detailed analysis of step-dowm Cuk circuit and derivation of the formula was carried out, giving the design of inductors and capacitors. Then comparison between the step-down Cuk circuit and Buck circuit was given using the PSPICE software. Finally, the experiment results verify the excellent electrical performance of step-down Cuk.关键词
