Provided herein are systems and methods described related to a power module of a drivetrain system of an electric vehicle. The power modules as described herein can include a sandwich structure that reduces a parasitic inductance of the power module through mutual inductance cancellation. For example, the power modules can include at least two current paths that overlap or are formed over each other in a sandwich like formation to form a power loop having an overlapping current path. The power loop can have an overall inductance value corresponding to a self-inductance of the first current path and a self-inductance of the second current path subtracted by a mutual inductance value of the overlapping current path.
