DC-DC DC-DC Converter Control Method for Photovoltaic System in Stand-alone Power Generation System

摘要

The present invention relates to a photovoltaic DC-DC converter control method in a stand-alone system. To minimize element damage and power outages due to a battery failure, battery voltage is checked in real time to control a DC-DC converter for photovoltaic power adjustment to output constant voltage when detecting an emergency situation so as to prevent a sharp increase of the voltage due to voltage stabilization of a DC-Link terminal in case of the battery failure, thereby increasing system stability and reliability.
