Abstract
According to one embodiment, a DC-DC converter for compensating a ripple in a photovoltaic-linked energy storage system and a control method thereof are disclosed. Particularly, a DC-DC converter for compensating for a ripple generated in a DC link connecting a single-phase inverter to a converter is disclosed. The DC-DC converter can compensate a ripple by using an active power component or the average voltage of a DC link voltage acquired from the DC link.
