The object of this paper is to design and analyze a proportional – integral (PI) control for positive output elementary super lift Luo converter (POESLLC), which is the start-of-the-art DC-DC converter. The positive output elementary super lift Luo converter performs the voltage conversion from positive source voltage to positive load voltage. This paper proposes a development of PI control cap...

This paper deals with Enhanced Phase Locked Loop Control scheme for Distributed Static Compensator (DSTATCOM) in the distribution system. The proposed control scheme based DSTATCOM eliminates current harmonics, maintains unity power factor at source, zero voltage regulation and load balancing. The Enhanced Phase Locked Loop (EPLL) Control scheme is based on Digital Signal Processing (DSP) which...

Since the conventional electro-mechanical converter of 2D valve had problems of step lose due to its small tooth-pitch angle, a novel rotary electromagnet with large tooth-pitch angle and coreless rotor structure was proposed. Combined with the approaches of magnetic circuit analysis, finite element simulation and experimental study, the static and dynamic characteristics of electromagnet inclu...

This project presents reactive power compensation in a distribution power system. DSTATCOM (distribution static compensator) is a reactive power compensator for power quality improvement in a three phase four wire distribution system. A voltage source converter (VSC) based DSTATCOM with a zig-zag transformer is used for the compensation of reactive power for voltage regulation along with load b...

This paper studies the problem of light splitter placement (LSP) and wavelength converter placement (WCP) in all-optical WDM networks to enable optimal provisioning of static and dynamic traffic through efficient photonic multicast connections. To solve the LSP-WCP problem under static traffic provisioning, an Integer Linear Programming model is formulated to achieve the optimal solution in the...

This thesis project examines the design of a monolithic audio-band digital-to-analog (D/A) converter with the objective of achieving a high signal-to-noise ratio, low analog die area consumption, and low static power dissipation. Issues relating to system design, digital signal processing, sigma-delta modulation, D/A topology selection, and switched-capacitor filter design are covered. The Dire...

Abstract A histogram-based built-in self-test (BIST) approach for deriving main characteristic parameters of an analog to digital converter (ADC) such as offset, gain and non-linearities is proposed. The BIST uses a ramp signal as an input signal and two counters as a response analyzer to calculate the derived static parameters. Experimental results show that the proposed method makes the hardw...

The article describes semi-symbolic methods for the analysis of control and signal processing systems, including static and dynamic uncertainties. This above mentioned semi-symbolic description of uncertainties is based upon affine arithmetic. A short introduction to affine arithmetic is given. As affine arithmetic is only able to describe static uncertainties, an extension for effects of dynam...

This paper proposes a built-in self-test (BIST) scheme for noise-tolerant testing of a digital-to-analogue converter (DAC). The proposed BIST calculates the differences in output voltages between a DAC and test modules. These differences are used as the inputs of an integrator that determines integral nonlinearity (INL). The proposed method has an advantage of random noise cancelation and achie...
