A boost Power Factor Correction (PFC) front end converter followed by a circulating current for the soft switching flows only through the auxiliary circuit and a In recent years, dc power supplies have been widely used in industrial Lr is delivered to the capacitor C1 via transformer T. iLr (t) decreases linearly. I believe that I understand how a starting capacitor is used with an induction mo...

We calculate the stopping power for heavy-ion diclusters moving in a strongly coupled two-dimensional electron gas system by using the local field corrected dielectric function at finite temperature. We obtain a parameterized local field correction factor based on a relation between the thermal compressibility and exchange-correlation energy in two-dimension. The interpolated parameter is deriv...

There are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. Although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

The objective of the electric utility is to deliver sinusoidal voltage at fairly constant magnitude throughout their system. This objective is complicated by the fact that there are loads on the system that produce harmonics currents. These currents result in distorted voltages and currents that can adversely impact the system performance in different ways. When harmonic currents flow through t...

Electric vehicle has received more and more extensive attention, which is one of the major development directions of motor vehicles using new energy sources. Electric vehicles are development promising green transports, and important means to solve energy and environmental problems. The construction of charging infrastructure is an important prerequisite for the advancement of electric vehicles...

The era of electronic devices in all loads due to the manufacturing technologies replaced many conventional electrical or mechanical loads including lighting loads where Light Emitting Diodes (LEDs) is becoming an emerging technique with many advantages. High frequency switching dc-dc converter is a new technology to control the load and the supply side simultaneously. Due to additional harmoni...

This paper proposes a hybrid decoupled power flow method for balanced power distribution systems with distributed generation sources. The method formulates the power flow equations in active power and reactive power decoupled form with polar coordinates. Second-order terms are included in the active power mismatch iteration, and constant Jacobian and Hessian matrices are used. A hybrid direct a...
