The impact of three-phase smart gate drivers on the performance and safety of PMSM and BLDC motor drives

Abstract

Three-phase smart gate drivers (SGDs) have revolutionized the control of high-performance permanent magnet synchronous motors (PMSMs) and brushless direct current (BLDC) motors. Smart Gate Drive offers an intelligent solution for driving and protecting the exterior Power MOSFETs. This feature allows system designers to adjust MOSFET slew rate, optimize switching and electromagnetic interference (EMI) performance, reduce bill of materials (BOM) numbers, automatically generate dead times, and provide additional protection for external power MOSFETs and the drive system. This makes them highly effective for use in demanding environments where motor performance and safety are critical and are widely used in industrial automation, automotive systems, drones and robotics.
