This paper proposes an improved stator flux control algorithm based on the torque feedforward control technique for interior permanent magnet synchronous motor (IPMSM). The proposed flux linkage control algorithm can prevent the d and q- axis voltages from saturation and improve the dynamic behavior. A lookup table is used in the torque feedforward control technique, which outputs the desired d and...
Si-C:H film has attracted a lot of attention recently for application in Si-based thin film solar cells, since its bandgap can be easily tunable over a range of 1.5–2.5 eV by simply varying the Si to C ratio in the film. Capacitively coupled SiH4/CH4/H2 plasmas are often employed for deposition of high quality Si-C:H film. A better understanding of the physical and chemical mechanisms in the plasma...
Summary form only given. Silicon carbide nanowires with junctions are considered to be of potential value in nanoelectronics. A simple method by catalyst-assisted vapor-liquid-solid reaction for producting Y-junction silicon carbide nanowires is described. The Y-junction silicon carbide nanowires are investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It...
