Abstract
Embodiments of an apparatus to increase the power efficiency of an electric motor load have been presented. In one embodiment, the apparatus includes a parameter detection circuit coupled to the electric motor load to detect one or more parameters of the electric motor load. Furthermore, the apparatus may include a power management controller coupled to the parameter detection circuit to receive the one or more parameters and to scale a voltage supply to the electric motor load in response to the parameters.
Claims20
An apparatus comprising:
- a parameter detection circuit coupled to an electric motor load to detect one or more parameters of said electric motor load;
