We describe a comparative analysis of the power consumption of optical cross-connect (OXC) equipment based on electrical and/or photonic matrix switching, which will be used for future large-capacity optical networks. The switch configurations used for both types of OXCs are also comprehensively discussed. For optical networks that accommodate traffic with a capacity of several Tb/s, the power ...

-This paper presents an optimal feed-back switching concept for the Unified Power Flow Controller (UPFC) based damping controllers for damping low frequency oscillations in a power system. Detailed investigations have been carried out considering switching between two optimal damping controllers; one with respect to modulating index of shunt inverter and another with respect to modulating index...

In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...

In modern design ows low power aspects should be considered as early as possible to minimize power dissipation in the resulting circuit. A new BDD-based design style that considers switching activity optimization using temporal correlation information is presented. The technique is developed as an approximation method for switching activity estimation. Experimental results on a set of MCNC and ...

Test pattern generator (TPG) is more suitable for built in self test (BIST) structures used for testing of VLSI circuits. The objective of the BIST is to reduce power consumption, switching time and power dissipation without affecting the fault coverage. Low power linear feedback shift register (LPLFSR) is employed for TPG in order to reduce switching activities. This paper presents multiplier,...

The paper introduces soft switching of a Boost Converter which can be included in the Electrical Vehicle technology. In order to raise the motor power rating, the DC link Vehicles, there is a great need for less component stress, smaller voltage of inverter up to 400V, and higher efficiency. The conventional Boost Converter generates switching loss at turn on and off thus the whole system's eff...

This work introduces a new non-isolated buck-boost DC-DC converter. Interleaved configuration of the suggested structure increases the voltage conversion ratio. The voltage rate of the suggested converter can be stepped-up and stepped down for lower values of duty-cycle, which causes to decrease in the conduction losses of the system. The voltage conversion ratio of the recommended structure is...

This paper analyses two schemes of single-stage diode-switched active filters used in new switching power supplies designs to improve the power factor. From the point of view of the power flow, the distortion reduction is based on the improvement of the power conversion processes. Most of the ca/cc switching power supplies consists of two separated parts: a rectifier – in most cases a diode bri...

The power requirements imposed on the amplifier by piezoelectric actuators is discussed. We consider a two-degree-of-freedom mechanical system driven by a piezoelectric stack for the purpose of analyzing power flow and power dissipation of four amplifiers. Two of the amplifiers are benchtop linear amplifiers. The other two amplifiers are based on switching topologies. The power consumption of a...
