Abstract
Appliance control with ground reference compensation is provided. Ground reference compensation can be desirable when a device or component of an appliance is powered by a higher power source, and is controlled by a controller that is powered by a lower power source. In such a situation, a voltage difference can develop between the ground references of the higher and lower power sources, which can affect accurate control of the device or component. In some cases, a measure related to the voltage difference between the ground references is first determined, and then the power/voltage that is ultimately delivered to the device or component is adjusted or compensated based, at least in part, on the determined difference.
