High-Power 10.5kW Motor Control

This design demonstrates a complete high-power synchronous/BLDC motor control system. It can support up to 10.5kW of power sourced from 3-phase Y-connected power mains. The unit consists of a high-performance Arm^® core microcontroller that handles motor control and power supply PFC regulation. These operations occur within an isolated environment and are controlled by optocoupled IGBT drivers for a set of high-voltage IGBT half bridges. The MCU device is controlled via an isolated RS-485 connection to an external control unit, with the option to use a CAN interface.

System Benefits:

• Complete system with single line control that is possible to scale up to eAI features for predictive maintenance
• Controls for the motor and power supply PFC only require a single RA6T2 MCU
• Control unit connection via RS-485 or CAN interface
