Objective: To meet the ART (autonomous rapid rail transit) system largepower charging needs, a new structure for ART charging device is proposed, which can be installed within an integrated intelligent boxtype charging station, avoiding noise and interface problems caused by the installation at passenger platform. Method: The system structure of the ART fast charging device includes inputside AC circuit interrupter, precharge circuit, networkside filtering circuit, PWM (pulse width modulation) rectifier circuit, Buck DC (direct current) conversion circuit and DCside filtering circuit; PWM rectifier realizes AC to DC power conversion; DC Buck conversion realizes DC voltage output meeting the ART onboard energy storage component charging mode of constant voltage, constant current and constant power; precharge circuit reduces the closing striking during system operation; networkside filtering reduces the harmonic current flowing into the power grid; DCside filtering uses inductance L and capacitance C to constitute a lowpass filter to filter out the output highfrequency component and reduce the output ripple current to the energy storage medium. Result & Conclusion: Through simulation and type selection calculation, the charging device uses dualloop control to improve system dynamic performance, the active damping technology to effectively suppress resonance, the forward and reverse rotation dualphase lockedloop to realize gridside adaptive control, system control and protection to manage Buck and PWM rectifier, and ultimately achieves constant voltage and current limitation control. The charging device is successfully applied in Zhuzhou ART phase I project, project vehicle launch verifies that the charging device can safely and efficiently charge ART vehicles.
