Abstract:
Provided a DC-DC converter and a two-stage power converter including the same. The DC-DC converter includes a plurality of active switches. Some of the plurality of active switches operate with a variable duty ratio D, and the remaining active switches operate with a fixed duty ratio. An input-output voltage conversion ratio of the DC-DC converter is determined based on the variable duty ratio D and an output of the DC-DC converter is controlled by adjusting the variable duty ratio D.

Claim (Index 3):
The DC-DC converter of  claim 1 ,\n wherein the DC-DC converter includes a first inductor and is formed of a buck-boost converter, wherein, when the second switch is an active switch, the first switch and the second switch operate alternately with variable duty ratios of D and 1-D respectively, wherein the third and fourth switches operate alternately with the fixed duty ratio of 0.5, and wherein operation conversion between a buck converter and a boost converter is performed at a time point at which an input voltage and an output voltage of the buck-boost converter become equal to each other.
