The design procedure of low-sensitivity second-and third-order class-4 Sallen and Key active resistance-capacitance (RC) allpole filters, using impedance tapering, has already been published. There a ladder structure in the positive feedback loop of an operational amplifier was used. In this paper desensitization using impedance tapering is applied to class-3 circuits with negative feedback ref...

This paper presents a new approach for realizing a smart, fault tolerant, controllable and asset efficient power grid through the use of massively-dispersed mass-manufactured communicationsenabled sensor, power-converter and actuator networks. One example is ‘Smart Wires’, implemented using many modules of a Distributed Static Series Compensator (DSSC) device that can be clamped on to existing ...

Abstract Electronic loads are a family of power converters which can be used as a variable impedance load in different applications. This paper analyzes high efficiency zero-voltage electronic loads based on the quasi Z-source converter topology .The proposed topology operate as an ideal current source which enables the operation of the zero input voltage. It can achieve a high efficiency of mo...

Space Vector Modulation (SVM) Technique has become the most popular and important PWM technique for three phase Voltage Source Inverters. Z-Source Inverters have the ability to boost the dc link voltage, thus increasing the output ac voltage beyond the values reached by conventional inverters. The enhanced ratio from ac output voltage to dc link voltage is possible due to an impedance network c...

General block diagram models are proposed for PWM DC-DC converters in continuous and discontinuous conduction modes with fixed switching frequency. Both current mode control and voltage mode control are addressed in these models. Based on these models, detailed nonlinear and linearized sampled-data dynamics are derived. Asymptotic orbital stability is analyzed. Audio-susceptibility and output i...

This paper will focus on the definition of the main performance characteristics that must have a converter power cell to fit the above mentioned application range. Starting with the establishment of the relevant trade-off parameters, in terms of power handling capability, input and output operational voltage ranges (both in nominal and emergency conditions), conducted emissions, bus capacitor a...

This paper presents an analysis and a novel control scheme for a doubly-fed induction generator (DFIG) based wind energy generation under unbalanced grid conditions. The control objectives are: (i) to limit the rotor currents, (ii) to suppress ripples in the torque and (iii) to suppress the dc-link voltage fluctuation through converter controls. Negative sequence compensation techniques by one ...

Wearable thermoelectric generators (TEGs) harvest thermal energy generated by the body to generate useful electricity. The performance of these systems is limited by (1) the small working temperature differential between the body and ambient, (2) the desire to use natural air convection cooling on the cold side of the generator, and (3) the requirement for thin, lightweight systems that are com...
