  • Patent number: 7808398
    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.

  • Publication number: 20090140874
    Abstract: Methods and apparatus for controlling power to a load device. The apparatus include a standby loss prevention module or a transformer system including the module. The module and system are directed to sensing load requirements and controlling a transformer accordingly to reduce power consumption when the load is in a stand by mode. One method includes interposing a control switch between an electrical supply and a load device, determining when the load device requires full-level operational power, activating the control switch to interpose a step-up transformer between the electrical supply and the load device, providing full-level operational power to the load device, and deactivating the step-up transformer when the load device is not in use.
