Zusammenfassung:	The invention provides an intelligent bus coupler device applied to a direct current power supply system for a station. The intelligent bus coupler device comprises a DC/DC power supply conversion module and a super capacitor bank, the two ends of the DC/DC power conversion module are connected between the I-section DC bus and the II-section DC bus, and each of the two ends of the DC/DC power conversion module is connected with a super capacitor bank; when the I-section direct current bus voltage and the II-section direct current bus voltage are normal, the two ends of the DC/DC power supply conversion module have no output; when the voltage of the I-section DC bus or the voltage of the II-section DC bus drops, the DC/DC power conversion module is switched on, and normal operation of the voltage of the I-section DC bus or the voltage of the II-section DC bus is guaranteed. According to the invention, a DC/DC power supply inversion technology is adopted for inversion output and is bridged between two sets of d
