ABSTRACT:
A transformer system for sensing load requirements and controlling a transformer accordingly to reduce power consumption when the load is in a stand by mode. One embodiment of the system includes a transformer implemented to receive an input and transform the input for use by a load, a sensor connected between an output of the transformer and the load, a communication link including the sensor and being connected between the transformer and the load, and a control switch connected to the transformer and sensor through the communication link. The sensor detects a mode of load operation and communicates a corresponding load mode signal over the communication link.
