Abstract
Disclosed is a low noise, non-isolated DC-DC converter for providing a non-inverted (i.e., the same polarity as an input voltage) output voltage of any desired voltage by stepping-up/down the input voltage. It comprises an input coil L, an input capacitor Cand a second intermediate coil Lmconnected in series between both ends of the input voltage source, an output coil L, an output capacitor Cand a first intermediate coil Lmconnected in series between both ends of a load Ro, a switching device S connected between a node a of the Land the Cand a node b of the Cand the Lm, and a diode D connected between a node d of the Cand the Lmand a node c of the Cand the L
