PROJECT TITLE :

87% Overall High Efficiency and 11 μA Ultra-Low Standby Current Derived by Overall Power Management in Laptops With Flexible Voltage Scaling and Dynamic Voltage Scaling Techniques

ABSTRACT:

The proposed overall power management in laptops will improve overall power conversion efficiency by the flexible voltage scaling (FVS) technique in cooperation with conventional dynamic voltage scaling (DVS) technique. The FVS technique separates the controller into two components. One may be a easy primary aspect controller and the other is emerged into the power management unit in the laptop for getting direct power management from the microprocessor. twelve% light load potency and 7% peak potency are improved compared to traditional style with the DVS technique only but without the FVS technique. Furthermore, inexperienced mode is proposed to effectively reduce chip quiescent current to 11μA and to suppress power loss to ten mW in ultra-light load, that is much smaller than 500 mW standby power outlined by the restriction of Energy Star Standard and forty mW of state-of-art industrial products.
