Analytical Modeling of Photovoltaic Systems Under Partial Shading Conditions Incorporating Bypass and Blocking Diodes Influence

open access: yesInternational Journal of Energy Research, Volume 2025, Issue 1, 2025.
This paper presents an innovative analytical model for photovoltaic (PV) systems operating under partial shading conditions (PSCs). The model is developed through a detailed analysis of the current–voltage (I–V) curves of PV systems affected by PSCs and employs a straightforward computational algorithm by adjusting every time the number of cells or ...

MTPA With Pseudo‐FOC Strategy–Based BLDC for Minimization of Copper Loss and Torque Ripple

open access: yesJournal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
Brushless DC (BLDC) motor drives are extensively preferred in the automotive industry for their high torque‐to‐weight ratio. In conventional BLDC drives, the torque ripples are high due to 120° conduction mode operation and nonideal back EMF. To minimize the torque ripple in BLDC drives, a flux trajectory is employed based on the extension Park ...
