In order to improve the efficiency and reliability of aging process, a real-time measurement & con-trol system for multiplex aging current of aluminum electrolytic capacitor is designed. The system is composed of aging, measure & control, serial communication circuit and PC software. Using MSP430F2274 as the core controller, this system can measure mass capacitors through the parallel measurement and channel switching of multiple aging current, and the fault capacitors will be distinguished automatically. Test result shows that the identification accuracy rate reaches 100%, which meeting and exceeding the design target.
