Abstract

The present invention is provided with the following: an AC / DC switching circuit (12) for switching the destination of power supply in accordance with the class of power being supplied from an overhead line (2); a transformer (14) for stepping down an inputted alternating current voltage; a tap changer (15) for switching a tap position of the transformer (14); a CNV (17) for converting the output of the tap changer (15) to a direct current voltage; an AC contactor (16) for opening and closing a power supply route between the tap changer (15) and the CNV (17); an FC (18) for storing either the output of the CNV (17) or the output of the overhead line (2); a CH (21) for stepping up the output of the FC (18); an FC (22) for storing the output of the CH (21); an INV (24) for converting the output of the FC (22) to a desired alternating current voltage; an AC / DC switching circuit (12); a DC contactor (19) that is connected between direct current buses (20a, 20b) connecting the FC (18) and the CH (21), and opens and closes a power supply route between the AC / DC switching circuit (12) and the CH (21); and a control unit (30) for controlling the tap changer (15), the AC contactor (16), the DC contactor (19), the CNV (17), and the CH (21) on the basis of information about the overhead line voltage as well as external command information.

Description

technical field [0001] The invention relates to an electric car main circuit system. Background technique [0002] In recent years, overseas (especially in the European market), due to the unification of the European railway network and the improvement of environmental awareness, it has been proposed to support various overhead line voltages (for example, AC15kV-16.7Hz, AC25kV-50Hz, DC1.5kV , DC3.0kV) trams, and thus hope to be equipped with a tram main circuit system that can support this multi-power supply. [0003] On the other hand, for a plurality of multi-power sources that can support the above-mentioned AC and DC, more specifically, any one of the AC power source and the DC power source can be supported, and at least one of the AC power source and the DC power source can be supported. The applicant searched the relevant technical literature for the electric car main circuit system with AC and DC multi-power sources, but failed to find appropriate literature containi...
