IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.The position measurement angle error (contains measurement delay angle and periodic angle error) plays a significant role in PMSM drives, especially when the motor is rotating in the flux weakening (FW) region. In this paper, the impact of the position angle error on the performance of the PMSM drives for EPS in a wide speed range has been elaborated ...

International Journal of Energy Research, Volume 2025, Issue 1, 2025.This study presents a novel micro‐combustor (MC) design called micro‐trapped vortex combustor (MTVC) for micro‐thermophotovoltaic (MTPV) devices used in small‐scale electricity generation. Traditional MC designs struggle to operate efficiently under ultra‐lean regimes due to flame quenching, limiting their performance.
