In this article, asymmetrical modular multilevel converter (A-MMC) topology using mixed cell (SM) with DC-side fault blocking capability and the reduced component count is proposed. The mixed cell submodule is made up of a full-bridge (FB-SM) and a half-bridge (HB-SM) with asymmetric capacitor voltage based on geometric propagation (GP) ratio. Each mixed cell submodule can […]
Side-channel attacks are attacks against cryptographic devices that are based on information obtained by leakage into cryptographic algorithm hardware implementation rather than algorithm implementation. Power attacks are based on analyzing the power consumption of a corresponding input and obtaining access to this method. The power profile of the encryption circuit maintains an interaction with the […]
Load frequency control is an important factor of supplying quality electricity in an interconnected power system. As a result, an optimally tuned Proportional-Integral-Derivative (PID) controller is proposed in this work to eliminate frequency errors caused by unexpected load changes while maintaining tie-line power exchange. The PID controller is tuned using several optimization techniques such as […]
In different medical applications, physical stimulation techniques are used to assist the treatment and improve the treatment conditions from different perspectives. They can accelerate the healing process and stimulate biological processes and healing mechanisms. In oral and maxillofacial reconstruction, one of the widely used physical stimulation techniques is Low-Level Laser Therapy (LLLT). LLLT is a […]
During peak demand hours, hydroelectric energy is one of the most significant sources of energy. Power sector restructuring has increased competition among the country’s electricity providers. Estimating the future price of energy is critical for producers in order to enhance investment profit and make better use of resources. One of the most significant technologies of […]
Dielectric Barrier Discharges (DBDs) are self-sustaining electrical discharges in electrode configurations containing an insulating material in the discharge path. Dielectric barrier discharge is considered a new method to produce plasma, which is of interest to researchers in various fields. In this article, electrical breakdown and plasma formation with argon atmospheric pressure gas are simulated. To […]
The use of solar energy has begun to be developed in PLTS, but the photovoltaic module electricity produced is not at maximum output power. To increase the efficiency of the photovoltaic module, Maximum PowerPoint Tracking (MPPT) technology is used. Differences in the level of solar energy irradiation can cause the output power of the solar […]
A compact, wideband, low cost, high radiation efficiency and planar half mode substrate integrated waveguide (HMSIW) horn antenna is proposed in this work. For the first time, HMSIW is used to design a horn antenna. By using HMSIW waveguide structure instead of Substrate Integrated Waveguide (SIW), the impedance bandwidth of antenna is increased significantly. The […]
Single-Point Diamond Turning (SPDT) has been widely used in manufacturing of optical components for critical applications including military, defense, aerospace, computer science, electronics, medical, and dental. Magnetic Field (MF) assistance is a recent non-conventional assistive technique that could be used during SPDT process to improve the machining conditions. Recent experimental studies show that using MF […]
The addition of renewable energy sources to the traditional distribution network has transformed the centralized unidirectional power source into two-way and multiple power source system. This will improve overall system’s reliability and also reduces the down time that are associated within the radial distribution system. This paper investigates the impact of distributed energy sources like […]
