Current-Controlled Phase Retardation Plate [PDF]
Applied Optics, 1975 A plate of fused quartz mounted in the jaws of a magnetic clamp serves as a current-controlled phase retardation plate. The current to the clamp controls the stress on the quartz plate, and hence the amount of stress-induced birefringence. The device described here can be used in a dc mode as a fixed phase retardation plate or in an ac mode as a ...

Design and Development of Low Torque Ripple Variable-Speed Drive System With Six-Phase Switched Reluctance Motors [PDF]
, 2018 Switched reluctance motor (SRM) drives conventionally use current control techniques at low speed and voltage control techniques at high speed. However, these conventional methods usually fail to restrain the torque ripple, which is normally associated ...
