| Abstract: | In this paper, two kinds of switched inductor Buck units are constructed by analyzing the energy storage components in a Buck converter and a Buck-Boost converter. The working principle for Buck units is analyzed, and the dual relationship between the structure of the Buck switched inductor and that of the Boost switched capacitor is discussed. The pre-stage Buck unit is extracted from a quadratic Buck converter and further combined with the two Buck switched inductor units, thus proposing a novel combined Buck converter with a Buck unit. By analyzing the working mode, working waveforms and various parameters of this converter in continuous conduction mode(CCM) and discontinuous conduction mode(DCM), its magnetic components are magnetic integrated to reduce the inductor current ripple. Finally, the theoretical analysis was experimentally verified. |
