Title:

TRAMCAR MOTIVE POWER SYSTEM AND CONTROL METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2015/135330

Kind Code:

A1

Abstract:

Disclosed are a tramcar motive power system and a control method thereof, the system comprising a fuel cell (11) connected to a unidirectional direct-current converter (14), a super capacitor (12) connected to a first bi-directional direct-current converter (15), and a power battery (13) connected to a second bi-directional direct-current converter (16), wherein the unidirectional direct-current converter (14), the first bi-directional direct-current converter (15) and the second bi-directional direct-current converter (16) are connected to an inverter (18) via a direct-current bus (17); the inverter (18) is connected to a motor of the tramcar; the fuel cell (11), the super capacitor(12), the power battery (13), the first bi-directional direct-current converter (15), the second bi-directional direct-current converter (16), and the inverter (18) are connected to a main control unit (19); and the main control unit (19) is connected to a control device of the tramcar. The super capacitor (12), the fuel cell (11) and the power battery (13) are cooperated to supply power, so that the disadvantages of insufficient energy of the super capacitor (12) and insufficient power of the power battery (13) are solved, and the disadvantage complementation of the energy storage components is achieved, the fuel cell (11) and the power battery (13) are mutually redundant so as to realize emergency rescue under a fault condition of a power supply component.
