  1. 1. High-Frequency Voltage Distribution Modelling of a Slotless PMSM from a Machine Design Perspective

    University essay from KTH/Elkraftteknik

    Author : Patrik Brauer; [2018]
    Keywords : Windings; drives; transients; surges; steep-fronted; slotless; litz-wire; effective relative permeability; Lindningar; elektriska drivlinor; transienter; spänningspulser; litz-tråd; effektiv relativ permeabilitet;

    Abstract : The introduction of inverters utilizing wide band-gap semiconductors allow for higher switching frequency and improved machine drive energy efficiency. However, inverter switching results in fast voltage surges which cause overvoltage at the stator terminals and uneven voltage distribution in the stator winding. READ MORE

  2. 2. Spectral time domain induced polarization : factors affecting spectral data information content and applicability to geological characterization

    University essay from Lunds universitet/Geologiska institutionen

    Author : Azadeh Rezvani; [2015]
    Keywords : Liikavaar; geology; geophysics; resistivity; induced polarization; Aititk mine; AarhusInv; Earth and Environmental Sciences;

    Abstract : The geo-electrical survey (resistivity and induced polarization) with different settings, arrangements, time base, spreads and waveforms (50% and 100% duty cycle waveform) was carried out over the Liikavaara depo-sit, near the Aitik mine, in northern Sweden and all the measured data was inverted in two different softwares: Res2Dinv and AarhusInv. Surveys of induced polarization (IP) often contain data of low quality, due to the high sensitivity against noise sources and coupling effects. READ MORE

  3. 3. Investigation and Study of Crosstalk

    University essay from Linköpings universitet/Linköpings universitet/Fysik och elektroteknikTekniska högskolan

    Author : Krishna Prasad Rao Pasupuleti; [2015]
    Keywords : Överhörning; Crosstalk; Electricfield coupling; magneticfield coupling; capacitiv coupling; kapacitiv koppling; Inductive coupling; induktiv koppling.;

    Abstract : Crosstalk is defined as an unwanted coupling between the conductors. By this it is meant that signals from one of the signal conductors (a generator in this case) are coupled to another signal conductor (receptor), or conductors (receptors), depending on the number of conductors in the vicinity of the generator.

  4. 4. Cable Monitoring Unit : Safety Ground Detection Through Capacitive Coupling

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Mattias Norman; [2014]
    Keywords : capacitive coupling; block heater; car; cable detection;

    Abstract : Electronically monitoring whether or not your car block heater is connected to a mains outlet might at first seem like an arbitrary task. A device installed in the comfort of the car seating area, which tells the user at every startup whether or not his/her car is connected to a mains outlet, could have market appeal though. READ MORE

  5. 5. An Input Amplifier for Body-Channel Communication

    University essay from Linköpings universitet/Linköpings universitet/ElektroniksystemTekniska högskolan

    Author : Md Hasan Maruf; [2013]
    Keywords : Body-Channel Communication; Analog Front End; Capacitive Communication; Preamplifier; Schmitt Trigger; Body Area Network;

    Abstract : Body-channel communication (BCC) is based on the principle of electrical field data transmission attributable to capacitive coupling through the human body. It is gaining importance now a day in the scenario of human centric communication because it truly offers a natural means of interaction with the human body. READ MORE
