Adaptive hysteresis band control for constant switching frequency in DTC induction machine drives
Constant switching frequency direct torque control induction machinedrive torque ripple
2010/10/12
It is fairly well known that direct torque control (DTC) exhibits fast dynamic torque response, a property that originates in the fact that torque and flux is directly controlled by instantaneous spac...
n-GaAs Band-Edge Repositioning by Modification with Metalloporphyrin/Polysiloxane Matrices
Band-edge positions Polysiloxane Metalloporphyrin Modification n-GaAs Photoelectrochemistry
2010/12/7
Tetra(-4-pyridyl)porphyrinatomanganese(III)sulfate, MnP, (in the forms of MnIII and MnII mixture), was embedded into a polysiloxane polymer matrix and attached to the surfaces of n -GaAs wafers. The n...
Dependence on the Partial Pressure of Oxygen on the Shift in the Energy Band-gap of CdO Thin Films in the Visible Region
CdO thin films Shift in the energy band-gap Partial pressure of oxygen
2010/12/8
In this paper, the dependence on the partial pressure of oxygen of the shift in the energy band-gap of CdO thin films for the visible region is investigated from the theoretical point of view on an ex...
