Reference design for three-phase motor drives based on Intelligent Power Module (IPM)


  • 850W Intelligent Power Module (IPM) Motor Driver
  • Compatible with Three-phase Motors: PMSM, BLDC or ACIM
  • Cross-conduction, Overcurrent, and Thermal Protection, Embedded in Power Module
  • Highly Integrated Power Module with Power Stage for a High Voltage 3-phase Inverter

The SECO-1KW-MCTRL-GEVB is a complete reference design for three-phase motor drives, featuring the NFAQ1060L36T intelligent power module.

Rated for 230 V(AC) input voltage and delivering up to 850 W power the reference design includes all necessary system blocks for a complete motor drive solution: EMC filtering and rectification stage, interleaved two-channel PFC, auxiliary power supplies, three-phase inverter, measurement, and protection. The graphical user interface ensures an easy startup for evaluation purposes running voltage/frequency control.
