This paper proposes a torque ripple reduction for brushless DC (BLDC) permanent magnetic (PM) motor drive based on the DC-link voltage pulse amplitude modulation (PAM). The proposed method improves ...

In this article, a general scheme of a 40-kV/2-kA resistive type dc superconducting fault current limiter (SFCL) is suggested, which could be utilized to suppress the surge current caused by ...

The major sources of hydrogen in the weld metal deposited with a tubular wire are (Boniszewski, 1992): moisture in the flux, hydrogenated flux ingredients, residual lubricant on the wire surface, ...

In this hands-on project, we put the INGCO 160A DC Inverter welding machine to the test by fabricating a fully functional steel grappling hook. Along the way, we evaluate the welder’s arc ...
