Design of PV charge and discharge controller in insulator monitoring system

This paper applies the solar photovoltaic power generation to supply the power to the insulator power line detection system. The paper control the charging and discharging of the battery through the DC / DC, voltage and current regulation feedback circuit. This system has finished the anti-lightning of protection of the battery, overcharge protection, charge overcharge protection and anti-reverse polarity protection. The power supply can meet the actual requirements through the experimental simulation analysis.
