Abstract: PURPOSE: A multilevel DC/DC converter is provided to minimize a switching loss by switching a zero current. CONSTITUTION: A multilevel DC/DC converter(100) includes a DC input voltage(110), a reactor(120), a plurality of condensers(130,131), and a switch(140). The reactor smooths the current which flows in a multilevel DC/DC converter. The reactor is connected to a DC input voltage and is an air core reactor. A plurality of condensers is serially connected to the reactor. A switch is connected between the reactor and the plurality of condensers and alternatively applies the DC input voltage to the plurality of switches.
