The invention relates to a driving motor control system, in particular to a gallium nitride controller for a new energy automobile. Comprising an installation carrier assembly, a sealing cover screwed on the installation carrier assembly, a power driving assembly fixed in the installation carrier assembly, an input electromagnetic coupling compatible device electrically connected with the power driving assembly, and a signal decoding deck assembly and a three-phase power assembly electrically connected with the power driving assembly. The power driving assembly comprises a gallium nitride power circuit board, a cooling assembly attached to the back face of the gallium nitride power circuit board and a module driving unit attached to the front face of the gallium nitride power circuit board. The gallium nitride power circuit board comprises a current inversion circuit board, an input switching current conductor integrated on the front surface of the current inversion circuit board, an AC output copper column, a plurality of driving pins, and a plurality of gallium nitride power devices integrated on the back surface of the current inversion circuit board. Compared with the prior art, the problems of low power density and low efficiency are solved, and the economical efficiency of an electric driving system is kept.
