This paper presents a novel way of generating the reference currents for an active filter and/or a static compensator. A compensator structure is proposed which is capable of balancing an unbalanced delta-connected load that may also draw harmonic currents. In addition to balancing the load, the supply side power factor is also made unity. The theory of instantaneous symmetrical components is u...

We study a model of a covalent band insulator with on-site Coulomb repulsion at half filling using dynamical mean-field theory. Upon increasing the interaction strength the system undergoes a discontinuous transition from a correlated band insulator to a Mott insulator with hysteretic behavior at low temperatures. Increasing the temperature in the band insulator close to the insulator-insulator...

the equilibrium moisture content is an important parameter for several post-harvesting operations for pistachio nuts, such as drying processes and storage. in this re-search the adsorption and desorption equilibrium moisture content were determined for two major varieties of iranian pistachios at 11 to 85 percent relative humidities and a con-stant temperature of 50°c. a significant hysteresis ...

This paper proposes a new control strategy for single-phase voltage source inverters that does not rely on switching based Pulse Width Modulation. The technique is similar to conventional current hysteresis control, but instead of the output current, low-pass-filtered inverter utilised as feedback signal. Nevertheless, instants are determined by predefined band, rather low-cost Complex Programm...

Abstract The electrical stability and reliability of two-dimensional (2D) crystal-based devices are mainly determined by charge traps in the device defects. Although nanobubble structures as defect sources 2D materials strongly affect performance, local charge-trapping behaviors nanobubbles poorly understood. Here, we report a Fermi-level hysteresis imaging strategy using Kelvin probe force mic...

The hysteresis motor is so named because it is producing mechanical torque utilizing the phenomenon of hysteresis. The rotor of a hysteresis motor is a cylindrical tube of high hysteresis loss permanent magnet material without windings or slots. This paper presents the design of a hysteresis permanent magnet motor using the finite element method. The rotor of the machine consists of 36% Cobalt ...

This work presents hysteresis control applied to UXE-type inverter topology with a PI (Proportional Integral) controller, where the gains are derived by Particle Swarm Optimization (PSO). The investigated UXE can generate thirteen-level output voltage waveform, which results in lower switching losses. It boost 1.5 times input DC source voltage. Satisfactory operation is ensured employing twelve...
