  1. 1. Mitigation of Background Harmonic Amplification at PCC Using Active Filtering of STATCOM

    University essay from KTH/Elkraftteknik

    Author : Luai Malki; [2017]
    Keywords : FACTS; Hybrid-STATCOM; TSC; TSR; VSC; passive filter; active filter; PWM; MMC; passivity; input admittance; resonance; harmonics; ABB;

    Abstract : Shunt compensation devices have been a powerful candidate for expanding the limits of transmission facilities, allowing more active power transport and supporting voltage and overall stability of the network. An example of such devices is the Static Synchronous Compensator (STATCOM) which is based on Voltage Source Converter (VSC) which synthesizes output voltage and current for mainly reactive power compensation.

  3. 2. Ultra-low power circuits for power management

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Giuseppe Forestiere; [2014]
    Keywords : ;

    Abstract : Recent developments in energy harvesting techniques allowed implementation of completely autonomous biosensor nodes. However, an energy harvesting device generally demands a customized power management unit (PMU) in order to provide the adequate voltage supply for the biosensor. One of the key blocks within this PMU is a regulation DC-DC converter. READ MORE

  5. 4. Construction of a Low-Noise Amplifier Chain With Programmable Gain and Offset

    University essay from Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

    Author : Jonas Tallhage; [2013]
    Keywords : VGA; ADC; low-noise amplier; sensor; switched-capacitor; chopping amplier;

    Abstract : A low-noise, variable gain amplier chain was constructed for interfa-cing a sensor to an ADC. During the course of the work two dierent methods -switched-capacitor circuits and chopping circuits - for dealing with 1/f noise wereinvestigated during the course of the work. READ MORE

  6. 5. Design of a Low Power Cyclic/Algorithmic Analog-to-Digital Converter in a 130nm CMOS Process

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Ajith kumar Puppala; [2012]
    Keywords : Redundant Signed Digit; Correlated level Shifting; Low power; High Speed; Folded cascode;

    Abstract : Analog-to-digital converters are inevitable in the modern communication systems and there is always a need for the design of low-power converters. There are different A/D architectures to achieve medium resolution at medium speeds and among all those Cyclic/Algorithmic structure stands out due to its low hardware complexity and less die area costs.
