  1. 1. A Novel Two-Level Inverter Design for Efficient Energy Conversion in a Maglev Train Rail

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Oskar Zetterström; Stefan West Westholm; [2023]
    Keywords : IGBT; Inverter; Gate-driver; Prototype; Pulse width modulation; Sine wave; Maglev train; IGBT; Växelriktare; Grinddrivenhet; Prototyp; Pulsbreddsmodulering; Sinusvåg; Maglevtåg;

    Abstract : This report covers the construction of a prototype inverter system designed to power the rail of a maglev train, from component selection through simulations and power demands to mounting and wiring the components into a cabinet. The inverter is made with insulated gate bipolar transistors controlled with pulse-width modulated signals provided by a custom microcontroller. READ MORE

  3. 2. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Marco Giuliato; [2019]
    Keywords : ;

    Abstract : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

  4. 3. Maximum Inverter AC Current Prediction Based on Junction Temperature Calculation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Shuyu Ou; [2019]
    Keywords : IGBT; Inverter; Junction temperature; Current Limiter; IGBT; Växelriktare; Övergångstemperatur; Strömbegränsare;

    Abstract : Semiconductor devices are widely used in the automotive industry, and they are key components of the inverter and the converter in an electric vehicle. Thus, the concern of protecting the inverter and the converter from damaging operation has been raised. The junction temperature is one of the main considerations. READ MORE

  5. 4. Technical Feasibility Study of an IGBT-based Excitation System

    University essay from Uppsala universitet/Elektricitetslära

    Author : Johan Frisk; [2017]
    Keywords : Cabinet design; inverter cabinet; IGBT; excitation system; EMC; electrical connection; Skåpdesign; IGBT; magnetiseringssystem; EMC; elektrisk anslutning;

    Abstract : This thesis aims to design a cabinet to house some of the required hardware to realize a 1000 A IGBT inverter controlled static excitation system. In the thesis practical design considerations are identified and solved. The suggested excitation system requires a cabinet to house the inverters. READ MORE

  6. 5. Development of EMT Simulation Model to Use RMS Control Model

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Priya Kalikavunkal; [2016]
    Keywords : ;

    Abstract : Evolution is continuous and as a result, developments in semiconductors are endless. This led to the Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) converter termed as HVDC light. HVDC light is quite preferable because of its pros in the technology used as well as the application it is used for. READ MORE
