This article deals with the influence of distributed generation (DG) on distribution line losses with respect to voltage profile. The article focuses on the development of a control strategy to minimize the grid losses and assure fairness regarding reactive power contributions. As retail customers typically have no choice where they are located along a feeder, it seems unfair that only some of ...

In this paper, minimization of the total harmonics (THD) present in the output voltage of multilevel inverters is discussed . In order to reduce the harmonic contents of the inverter's output voltage the best approach is THD minimization. In multilevel inverters, if fundamental frequency switching strategy is considered,(each switch turning on and off once per output cycle), the switching angle...

This paper presents a novel low-cost, highly efficient, reliable and compact motor drive topology for residential and commercial application. The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC ...

In this paper, a nonlinear loss minimization control strategy for an interior permanent magnet synchronous motor (IPMSM) based on a newly developed sliding mode approach is presented. This control method sets force the speed control of the IPMSM drives and simultaneously ensures the minimization of the losses besides the uncertainties exist in the system such as parameter variations which have ...

In this paper an optimal damped input filter is designed based on a Genetic Algorithm (GA) for an electrolytic capacitor-less AC-AC converter. Sufficient passive damping and minimum losses in passive damping elements, minimization of the filter output impedance at the filter cut-off frequency, minimization of the DC-link voltage and input current fluctuations, and minimization of the filter cos...

Minimization of Boolean switching functions is a basic problem in the design of logic circuits. The designer first comes up with a switching funct.ion expressed in terms of several binary input. variables that satisfies tlie desired functionality, and then attempts t.0 minimize the function as a sum of products or product of sums. It turns out that a sum of products form of a switching function...

Currently, several soft switching topologies have been studied to achieve high power switching efficiency, reduced cost, improved reliability and reduced parasites. It is well known that improvement in power electronics systems always depend on advanced in power devices. The IGBT has been successfully used in a variety of switching applications such as motor drives and appliance control because...
