Maximum Power Transfer

Maximum Power Transfer

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

Main Methods:

Development of a DRL-based framework for adaptive decision-making in ISCPT.
Utilizing DRL to manage complex environmental states and dynamically adjust sensing, communication, and energy harvesting parameters.
Implementing robust, learnable beamforming strategies to infer achievable rate upper bounds.

Main Results:

The DRL-based ISCPT framework effectively manages system variables for improved performance.
Significant improvements in resource allocation, power management, and information transmission were observed.
