This manuscript proposes an improved DC-DC converter framework using hybrid control algorithm for minimizing brushless DC motor (BLDC) torque ripple (TR). At first, the modeling of is intended by enhanced Cuk (ECC). The function and performance are updated application switched inductor. In this way, system integrates two loops such as speed loop, which employed improving BLDC performance. Therefore, Invasive Weed Optimization (IWO) Local Random Search (LRS) proposed to enhance loop...

There is worldwide increasing demand of electric vehicle because stringent emission regulation. However, there are still many questions surrounding the development such as, milage, charging time and life span battery. In order to address these issues, it necessary develop a robust Energy Management System (EMS). This work aims propose hybrid energy storage system which can extend battery maintain better performance. Considering advantages high-power density flexible modular structure,...

Field-oriented control (FOC) of permanent magnet synchronous motor (PMSM) is extensively preferred in high-performance drive systems due to its distinct features like better power factor, high efficiency, higher density, torque volume ratio and low inertia. A voltage source inverter (VSI) generally used the PMSM. suitable pulse width modulation (PWM) technique has be VSI. In this paper, a comparative performance analysis vector-controlled PMSM with SPWM SVPWM techniques presented. The been...

Abstract An optimization approach for two-area power system with Unified Power Flow Controller (UPFC) is proposed in this paper. The method the Atomic Orbital Search (AOS) approach. applied to achieve full utilization of UPFC and keeps parameters uncertain. multivariable PI controller utilized control eliminates negative interaction controllers. combines two subsystems by converting algebraic subsystem using differential approximation, which leads a nonlinear system. provides efficient...

Microgrids are becoming inevitable in power systems due to the increased penetration of renewable generators and demand for clean sustainable energy. The ferroresonance problem cannot be discarded case a micro-grid with multiple especially islanded mode operation. An analysis about occurrence severe effects during islanding micro grid is presented this paper. A solar PV wind turbine modeled using MATLAB/Simulink software. overvoltage caused by analyzed an induction motor load. possibility...

Modulation strategies play a vital role in the control of inverters. Even though variety modulation are available only handful them both, simple to be easily implemented by programmable computers and capable provide satisfactory performance. A novel concept, which is comparatively effective, has been presented here extend most two level inverter any levels series connected This achieved utilizing concept de-multiplexing based on threshold detection modulating signal. In order demonstrate...
