DC-DC A DC-DC converter for photovoltaic linked energy storage system and control method thereof

摘要

According to one embodiment, disclosed are a DC-DC converter sensing a ground state and a control method thereof in a photovoltaic linked energy storage system. Specifically, the ground state may be sensed based on the magnitude of a voltage applied to resistance to provide a notification. The DC-DC converter includes a converting circuit, a ground sensing circuit, and a processor.
