1.1 Introduction

This EVM uses GaN technology to implement a 3-phase inverter controlled by the TMS320F28P650DK on the C2000 LaunchPad. The GaN inverter demonstrates the ability of GaN to operate at higher switching frequencies than traditional MOSFET motor drives. Phase current sensing leverages the latest precision isolated delta-sigma modulators in a QFN package. This design improves current sensing accuracy and eliminates problems associated with common mode transients. By default, the EVM operates without a heat sink but includes mounting holes for a custom heat sink if needed.

This user's guide describes the characteristics, operation, and recommended use cases of the BP-AMC0106-LMG-MD. This document provides examples and instructions on how to use the BP-AMC0106-LMG-MD board and included software. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the BP-AMC0106-LMG-MD. This document also includes a schematic, reference printed circuit board (PCB) layouts, and a complete bill of materials (BOM).
