Figure 1: The system block diagram (left) showing three main components: the two converter modules, each with a gate driver, and the controller. The power modules mounted on the cold plate (A), and then in the power core with gate drivers (B), are also shown outside the dual inverter enclosure (C). Handles and feet are provided for portability, (D) shows the 204 mm x 267.5 mm cross section

The traction drive is where nearly all of an electric vehicle’s (EV’s) energy is put to use. The drive system must, therefore, perform with the highest possible efficiency while occupying the smallest possible space with the lowest weight — all to maximize the EV range. With the use of dual drives to enhance tr
