The invention discloses a layout method of a SiC MOSFET converter and the SiC MOSFET converter. The layout method comprises the steps that an alternating-current port (7) of an SiC MOSFET module (1) is connected to a three-phase inductor (8) through a U-shaped busbar (11); the gate and the source of the SiC MOSFET module (1) is vertically inserted with an SiC MOSFET driving module (2); a direct-current port of the SiC MOSFET module (1) is vertically inserted with a direct-current busbar (3); the two sides of the direct-current busbar (3) are provided with capacitors (4); the SiC MOSFET driving module (2) is connected with a controller (5) and is controlled to drive the SiC MOSFET module (1). The SiC MOSFET driving module is vertically inserted into the gate and the source of the SiC MOSFET module, so that the connection between the SiC MOSFET driving module and the gate and the source of the SiC MOSFET module meets the switching speed of the SiC MOSFET module.
