Low voltage (LV) variable frequency drives (VFDs) have been applied to applications up to 2500 horsepower (HP). Medium voltage (MV) VFDs have been applied to applications as low as 150 HP. Traditional power system design practice suggests that motor crossover from low voltage to medium voltage is in the 200-600HP range.
