Parameter sensitivity analysis is usually required to select the key parameters with high optimal goal before optimization carried out, especially for flux-switching permanent magnet (FSPM) machines where lot of design should be considered. Unlike traditional studies on parameter sensitivity, which are generally experience- or statistics-based, and time-consuming, this paper proposes a method F...

A high-temperature superconducting (HTS) axial flux permanent magnet (AFPM) machine was designed, using bulks over the rotor surface and rare-earth magnets in middle of stator teeth. Because diamagnetic behavior HTS zero field cooling, leakage significantly reduces proposed compared to existing with mounting magnets. Three-dimensional finite element (FE) modelling used validate design performan...

In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

Direct torque control (DTC) minimizes the use of machine parameters [1, 2]. Among all methods of torque control in induction motor, direct torque control (DTC) seems to be particularly interesting being independent of machine rotor parameters and requiring no speed or position sensors [3, 4, 5]. In spite of its simplicity, DTC is capable of generating fast torque responses. In DTC the torque an...
