Introduction

The 11kW Dual Active Bridge (DAB) Demonstration Application, based on Microchips dsPIC33C family and Silicon Carbide (SiC) devices, supports rapid prototyping and code development. The primary target application is an automotive On-board Charger (OBC), but it can be used for any other industrial or telecom application demanding high-power, high-voltage dynamic bidirectional power supplies.

The board offers well-organized building blocks, including an input-buffer filter, power-conversion stage, output filter, auxiliary supply, dsPIC33 Digital Power Plug-In Module (DP PIMs), test points and a CAN bus interface. Half-bridge switching legs are supported through SiC FET Plug-In Modules (PIM).
