Inverters used to control a motor’s speed or torque — also known as variable frequency drives (VFDs) or adjustable speed drives — can induce unwanted motor shaft voltages that cause premature motor ...

All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings ...

The TIDA-00442 TI design provides a reference solution for detecting ground faults in inverter based drives. Inverter current is measured on both dc-positive and dc-negative buses using shunt ...
