The invention provides multifunctional integrated converter equipment and a control method thereof. The multifunctional integrated converter equipment comprises a step-down transformer, a filtering unit, a full-control power module and an isolation output module which are connected in sequence, the system also comprises a main control unit, and the main control unit is connected with the full-control power module. The full-control power module comprises a plurality of groups of unit controllers and power modules which are mutually connected, the unit controllers are connected with the main control unit, and the unit controllers are used for converting driving instruction signals of the main control unit into PWM signals and controlling on or off of transistors of the power modules. The device and the method can be compatible with a power supply system of the existing urban rail transit, the design cost is reduced, the capacity is large, capacity expansion is easy, and the cost is low. The equipment not only has a traction rectification function and a regenerated energy inversion feedback function, but also has reactive compensation and harmonic suppression functions, and can provide a power supply with more stable voltage and higher reliability for urban rail transit locomotives.
