The design of aviation battery charging and discharging system based on DSP

Aviation battery which is used for giving power to critical load of aircraft for an emergency situation is an important part of the aircraft airborne equipment Traditional battery charging equipments usually adopt simple methods such as constant current or constant voltage to charge battery without the ability of monitoring the status of battery in real time in the charging and discharging process. This imprudent approach usually leads to the over-charging as well as irreversible damage to the battery. For dealing with challenge problem, we intend to apply modern power electronics technology, high-frequency inverter technology and discharge depolarization timely technology to overcome those shortcomings mentioned above. At the same time, our major task focused on the hardware design based on DSP controller, including AC to DC circuit, full bridge inverter circuit, driver circuit, the rectifier filter circuit and so on. The simulation and experimental results show that the aviation battery charging equipment we designed can fulfill the practical requirement and has more advantages such as high effective and real-time status detection etc.
