Design of New Energy Marine Bidirectional DC-DC Control System
In order to adapt to the significant changes in the output voltage of solar panels during the day and night,and ensure the voltage stability of electrical equipment on the bus,a new energy marine bidirectional DC-DC control system is designed.The system uses STM32 as the main control chip,and the main circuit adopts a Buck-Boost topology structure.Isolation amplifiers are used to collect current and voltage signals in the circuit.The current and voltage signals are preprocessed and then converted into controlled parameters through internal A/D conversion in STM32.The control program is divided into two parts:soft start and normal operation.The test results show that the designed system meets the application requirements.
