電力システム
Document Type and Number:
Japanese Patent JP5602745
Kind Code:
B2
Abstract:
The present invention provides methods and apparatus for reducing power consumption. One method includes detecting the presence of an object, identifying whether the object is a valid device and restricting power if its not a valid device. Another method includes temporarily applying a low amount of power to the primary unit to detect a load, supplying more power to determine if its a valid secondary device, and restricting power if its not. An apparatus for reducing power consumption includes two power inputs, where the lower power input powers a sense circuit. A switch selectively decouples the higher power input from the primary subcircuit during detection mode and couples the higher power input to the primary subcircuit during power supply mode.
