A pseudorandom test patterns are generated using low power programmable generator with desired toggling levels and enhanced fault coverage gradient. A linear feedback shift register drives a phase shifter to produce binary sequence using preselected toggling (PRESTO) activity. Several controls of the generator are selected automatically for easy and precise tuning. For shaping the test power en...

This paper proposes a novel axial flux switching permanent magnet generator for small wind turbine applications. Surface mounted axial flux switching permanent magnet (SMAFSPM) machine is a new type of these machines that is introduced in this paper. One of the most important challenges in optimal designing of this kind of machines, is ease of construction and maintenance. One of the main featu...

We demonstrate a novel method of generating a multiwavelength pulse train by use of time-lens compression. In addition to pulse compression, this time lens simultaneously displaces the pulses according to their center wavelengths, resulting in a temporally evenly spaced multiwavelength pulse train. We further demonstrate a new aberration-correction technique based on the temporal analog of a sp...

According to modern grid regulations, doubly fed induction generator (DFIG) needs to operate without losing synchronism during grid faults. But, severe fault leads to rise in stator and rotor current to a higher value and generator will get damaged. Large oscillations in stator real and reactive power are produced and consequently large torque oscillations get developed. To overcome the above a...

The purpose of this paper is to establish a robust and low-cost structure for a generator connected to an isolated load for wind applications. In a hybrid excitation synchronous generator (HESG), the excitation flux is created by both permanent magnets and excitation coils, so the output voltage can be controlled by the DC excitation field. For isolated loads, it is then possible to use a simpl...

A new design approach of superconducting wind generator having both axial and radial air gaps between stator and superconducting rotor winding is selected for this simulation work. This paper deals with the simulation of magnetic flux distribution in stator and rotor coil of th...
