Zusammenfassung:	There is provided a multi-level converter capable of a multi-level converter capable of outputting power having various voltage levels by using a simple circuit with respect to a single input power supply, an inverter having the same, and a solar power supply apparatus having the same. The present invention provides a multi-level converter including a first buck-boost unit having a single power switch switching an input power supply and outputting a first power having a voltage level varied according to the switching of the power switch, a bypass unit outputting a second power having a voltage level of the input power supply, and a second buck-boost unit sharing the power switch with the first buck-boost unit and outputting a third power having a voltage level varied according to the switching of the power switch; an inverter having the same; and a solar power supply apparatus having the same.
