The paper presents the DQ axis with Fourier analysis (DQF) algorithm to identify harmonic quantities for hybrid power filters. This algorithm is a combination of the advantages of DQ axis method and sliding window Fourier analysis (SWFA). This paper also presents the harmonic elimination by using the DQF algorithm for both three-phase balanced and unbalanced systems. The results show that the u...

ÐCut-through switching promises low latency delivery and has been used in new generation switches, especially in high speed networks demanding low communication latency. The interconnection of cut-through switches provides an excellent network platform for high speed local area networks (LANs). For cost and performance reasons, irregular topologies should be supported in such a switch-based net...

Bidirectional topologies are usually preferred over unidirectional ones. However, recent works have demonstrated that RUFT, a traffic-balancing routing algorithm on a Unidirectional Multistage Network (UMIN), can perform as well as a Bidirectional Multistage Network, but significantly reducing both implementation and operating costs. RUFT is a simplification of the k-ary n-tree topology, the mo...

Pulse Width Modulation (PWM) techniques are increasingly employed for PWM inverter fed induction motor drive. Among various popular PWM methods used, Selective Harmonic Elimination PWM (SHEPWM) has been widely accepted for its better harmonic elimination capability. In addition, using SHEPWM, it is also possible to maintain better voltage regulation. Hence, in this paper, an attempt has been ma...
