The invention discloses an integrated modular controller for an electric vehicle driving motor. The driving motor is a three-phase switched reluctance machine, the controller mainly comprises a control circuit, a driving circuit and a power conversion circuit, wherein the control circuit and the driving circuit both select surface-mounted package devices, the power conversion circuit employs an asymmetric half-bridge main circuit topological structure, a switch tube and a diode in a main circuit employ a mode that a plurality of tubes are connected in parallel, a switch tube and a diode, which are connected in parallel, in each bridge arm are fixed on a heat dissipation aluminum block to form an in-line structure, a DC-side capacitor of a power converter is formed by connecting a plurality of small-capacity electrolytic capacitors to substitute for an electrolytic capacitor with relatively large volume, and each bridge arm is consistent and symmetric in device installation and circuit layout so as to prevent stray inductance and non-uniform current sharing. By reasonable device type selection and layout, the whole control system is integrated onto a printed circuit board, the integration and the modularization of the controller are achieved, the cost and the volume of the controller are greatly reduced, the system reliability is improved, and the integrated modular controller has good engineering application and reference values on integrated development of the controller for the electric vehicle driving motor.
