A novel non-isolated Multi-level DC/DC (MLDC) converter using vertical interleaving technique is reported in this paper. This MLDC offers a wide range of voltage transfer ratio by using reduced number of low voltage power electronic devices and reduced size of the DC inductor, making this converter a potential candidate solution for high power Medium to Low Voltage (MV to LV) DC/DC conversion such as energy storage connection to Medium Voltage (MV) systems or drives. The derivation of the generic topology and power electronic device voltage rating selection have been given. Design considerations and all possible arrangement of the vertical interleaving sequences used in this MLDC has been introduced with mathematical expressions.
