Research on Small Base Station Photovoltaic Power Supply Inverter Based on STM32
With the development of 5G technology,the demand for small base stations is gradually increasing,but the power supply issues limit the deployment of small base stations.In order to solve the problem,the study designs a photovoltaic power supply inverter power supply,which mainly consists of control circuit,full bridge inverter circuit,filtering circuit,boosting circuit,and protection circuit.STM32 serves as a controller to output complementary PWM waves,and then the PWM waves will sent to the full bridge circuit through IR2101.The complementary PWM waves control the conduction and turn off of the two bridge arms,converting DC power into square wave signals.After filtering,the sinusoidal AC power will be put out,which is then boosted and supplied to the base station.Finally,a photovoltaic inverter power supply experimental platform is built,and experiments are conducted.The experimental results show that the designed circuit is feasible.The designed photovoltaic inverter power supply has a small volume,and good performance.So it has evident application value.
