Resumen:

The energy storage capacitor is the key component of the levitation chopper in the maglev train, and its state is related to the safe and stable operation of the maglev train. Based on the operating principle of the levitation chopper, this paper analyzes the main degradation mechanism of the storage capacitor, selects the capacitance capacity and the equivalent series resistance as the characteristic parameters, and proposes a state evaluation method of energy-storage capacitor based on the neural network. The capacity of the energy-storage capacitor and the equivalent series resistance are identified by the bus voltage, the bus voltage ripple and the load current. The effectiveness of the evaluation method was verified by experiments. © 2019 IEEE.
