Title:
DIRECT CURRENT BREAKER BRIDGE MODULE
Document Type and Number:
WIPO Patent Application WO/2016/107452
Kind Code:
A1
Abstract:
A direct current breaker bridge module, comprising an IGBT press-fitting unit (2), a capacitor bank (3), a laminated busbar (4), a control unit, an energy supply unit (7) and a support frame (8); the capacitor bank is electrically connected to the IGBT press-fitting unit via the laminated busbar; the capacitor bank is connected to the control unit and the energy supply unit; and the IGBT press-fitting unit, the capacitor bank, the laminated busbar, the control unit and the energy supply unit are located on the support frame. The direct current breaker bridge module eliminates a potential explosion risk of a traditional welded module in a failure state, improves integration of the module, reduces a total volume of the module, lowers voltage spike of the module when a large current is cut off, and also provides a larger heat dissipation area for the control unit.
