High-Power 10.5kW Motor Control

This design demonstrates a complete high-power synchronous/BLDC motor control system, supporting up to 10.5kW of power from 3-phase Y-connected power mains. It features a high-performance Arm^® Cortex^®-M33 MCU that manages motor control and power factor correction (PFC) regulation within an isolated environment. The system uses optocoupled IGBT drivers to control high-voltage IGBT half bridges. The MCU is controlled via an isolated RS-485 connection to an external control unit, with an option for a CAN interface.

System Benefits:

• Complete system with single-line control, scalable to eAI features for predictive maintenance.
• Efficient motor and power supply PFC controls managed by a single MCU.
• Flexible control unit connection options via RS-485 or CAN interface.
