Parallel hybrid excitation brushless direct current power generation system with reactive suppression effect

The embodiment of the invention discloses a parallel hybrid excitation brushless direct-current power generation system with a reactive suppression effect, and relates to the technical field of aviation and vehicle-mounted brushless direct-current power generation. The brushless direct current power generation system provided by the invention comprises a parallel hybrid excitation generator, a diode uncontrolled rectifier bridge, a filter capacitor and an excitation control system. The parallel hybrid excitation generator with the reactive power suppression function is formed by axially paralleling an electro-magnetic motor and a permanent magnet synchronous motor in parallel, wherein the electro-magnetic motor is connected with an armature winding in a delta shape, and the permanent magnet synchronous motor is of an open winding structure. According to the brushless direct current power generation system disclosed by the invention, the reactive power flow suppression between the electro-magnetic motor and th
