A New Method for Finding the Thevenin and Norton Equivalent Circuits
Engineering, 2010 The paper presents a new pedagogical method for finding the Thevenin and Norton equivalent circuits of a linear electric circuit (LEC) at the n-different pairs of terminals simultaneously, regardless of the circuit topology and complexity. The proposed method is appropriate for undergraduate electrical and electronic engineering students leading to ...

Energy Conversion and Economics, Volume 6, Issue 3, Page 196-212, June 2025.Abstract Constant power loads (CPLs) introduce negative impedance in direct current microgrids (DCMGs), which is a major challenge. This negative impedance can significantly reduce the overall damping of the system, making it less stable and harder to control. To address this issue, output virtual resistance (VR) shaping is commonly employed to enhance

Short‐Dipole Sensor Response Linearization Through Physics‐Informed Neural Networks
Bioelectromagnetics, Volume 46, Issue 4, May 2025.ABSTRACT Short‐dipole diode sensors loaded with highly resistive lines are commonly used to measure the time‐averaged square of the high‐frequency electromagnetic field amplitude directly. Their precision, simplicity, broadband, high dynamic range capability, and minimal scattering make them ideal for application in the near‐field of sources ...
