Hysteresis current control method is vastly used in PWM inverters because of simplicity in performance, fast control response and good ability in limiting peak current. However, switching frequency in hysteresis current control method with fixed bandwidth has large variation during a cycle and therefore causes non-optimal current ripple generation in output current. One of basic problems in imp...

This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

This article presents the analysis and design of a Class- $\text{E}_{\mathrm {M}}/\text{F}_{\mathrm {n}}$ power amplifier (PA). The high peak switch voltage factor classical {M}}$ PA is reduced by 27.3% through adoption notation="LaTe...

Abstract The synchronisation of magnetic tunnel junctions in the high frequency domain has attracted significant interest context novel computation paradigms, specifically neuromorphic spintronics and probabilistic computing. In this work, a design for coupling synchronization spin torque vortex oscillators (STVOs) is implemented. geometry comprises fabrication adjacent pairs STVO nanopillars (...

Variable speed drives (VSDs) use power electronic components as controlled switches which distort the sinusoidal current and voltage waveforms of AC grid due to harmonic injection at the point of common coupling (PCC). These harmonics and distortions are propagated through the power network and affect all other connected loads. So, the shunt active power filter (SAPF) is one of the proposed too...

Power quality (PQ) problems for renewable energy system (RES) is major challenge using these systems. Amplitude, frequency, and waveform important PQ parameters especially standalone or isolated In this paper we propose RES with wind turbine (WT) permanent magnet synchronous generator (PMSG) to feed different loads (liner, non-liner) through AC-DC-AC converter. The PMSG operate fuzzy logic iner...

This study evaluates the tissue integration and collagen network effects of HA-based soft filler Juvéderm Voluma XC in a rat model using novel three-dimensional (3-D) imaging platform image analysis algorithms. Rats were injected subcutaneously with 125 μL XC. After 4- or 12-weeks post-injection, second harmonic generation (SHG) signal autofluorescence within entire bolus was assessed TissueVis...
