Dynamic PoE Power Allocation for Enterprise PCs

The patent implements dynamic power allocation where the PSE continuously monitors power consumption of each PD and adjusts power distribution in real-time based on actual needs. This dynamic approach allows the system to provide high power when necessary while reducing power to minimize noise and cooling requirements during normal operation.

The system changes power delivery parameters dynamically by monitoring current power consumption levels and adjusting voltage/current allocation. The PSE modifies power delivery parameters based on monitored consumption patterns, enabling optimal balance between power availability and noise/heat generation.

The patent applies partial action by allocating power selectively based on actual consumption rather than providing maximum power to all ports simultaneously. The PSE monitors each PD's power needs and provides only the necessary amount, avoiding excessive power allocation that would require larger, more expensive power supplies.

The system implements feedback mechanisms where the PSE monitors power consumption from each PD and uses this information to adjust power allocation. This closed-loop feedback enables the power supply to be sized appropriately for actual usage patterns rather than worst-case scenarios, reducing cost and complexity.

The patent maintains continuous power management by monitoring power consumption throughout operation rather than performing one-time classification. This continuous monitoring enables ongoing adjustment of power allocation while maintaining compatibility with traditional PoE devices, combining the benefits of both approaches.

The system performs preliminary power classification compatible with traditional devices while simultaneously preparing for dynamic adjustment. The PSE initially classifies devices using standard methods ensuring compatibility, then transitions to continuous monitoring and dynamic allocation for enhanced flexibility.
