Abstract: In this paper, a novel sensorless control scheme for SCIG-based wind turbine systems, which utilizes cascaded second-order generalized integrators (SOGIs), is proposed. The DC offset and harmonics in the estimated rotor flux can be significantly… read more here.

Abstract: We demonstrate temporal contrast improvement through cascaded second-order nonlinear processes in a 340-µm BBO crystal. The process was initiated by second harmonic (SH) generation, followed by difference frequency generation (DFG) between the SH and the… read more here.
