Bidirectional converter for subway station

The utility model discloses a bidirectional converter for a subway station. The bidirectional converter comprises a plurality of parallel IGBT power modules divided into two groups, two parallel high-power controllable units and a secondary side double-winding boosting transformer, the direct current sides of each group of IGBT power modules are jointly connected to a fuse and then connected to a direct current power grid, and the alternating current sides are respectively connected to one winding of the boosting transformer after being filtered; the direct-current side of one high-power controllable unit is connected to a direct-current power grid, and the alternating-current side is connected to one winding of the boosting transformer; the direct-current side of the other high-power controllable unit is connected to the direct-current power grid, and the alternating-current side is connected to the other winding of the boosting transformer; and an output filter reactor, an alternating current sensor and a l
