A new type of MIN, Advanced Omega network, which using 4×4 switches, is proposed on the basis of the idea of the Delta network and the Omega network. In this paper, it is proved that 4×4switches have the better performance/cost ratios than 2×2 switches based on the current level of the VLSI technology. This paper expounds its topological properties and routing algorithm and makes performance...

Software-defined networking (SDN) enables controlling the behavior of a network in software, by managing the the forwarding rules installed on switches. However, it can be difficult to ensure that certain properties are preserved during periods of reconfiguration. The widelyaccepted notion of per-packet consistency requires every packet to be forwarded using the new configuration or the old con...

In high-power applications, opening switches play an important role. These switches are required to carry high currents (100 A-10 MA) and operate with short switching times ( l0ms-Ions). Moreover, before opening, the switch must conduct current to a parallel circuit branch (load) and withstand the voltage across the load. If there is no load in parallel to the switch, it must absorb all the ene...

In this paper, a new structure for cascade multilevel inverter is presented which consists of a series connection of several sub-multilevel units. Each sub-multilevel unit comprises of eight unidirectional switches, two bidirectional switches, and six DC voltage sources. For the proposed cascade topology, two algorithms are presented to produce all possible levels at the output voltage waveform...

In this paper a new design for 6 bit DMTL phase shifter with only 32 MEMS switches is proposed. The reduction in number of switches in ordinary 6 bit phase shifter from 63 to 32 is due to combination of one 5.625 degree for least significant bit and 11.25 degree for the rest of the switches. Decreasing the number of the switches reduces the die-size as well as loss of the CPW line. Analytical s...

Abstract – A novel parallel three-level zero voltage switching (ZVS) DC converter is presented for medium voltage applications. The proposed converter includes three sub-circuits connected in parallel with the same power switches to share load current and reduce the current stress of passive components at the output side. Thus, the size of the output chokes is reduced and the switch counts in t...

This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...

Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...
