1. 1. All-digital FPGA receiver : on Intel Stratix 10 TX

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Kim Persson; [2021]
   Keywords : FPGA; VHDL; Transceivers; Digital communication; ADC; PWM; QAM;

   Abstract : Ordinary digital receivers use analog mixers and conventional analog-to-digital converters. Thisthesis explores the possibility to build a receiver using an Intel Stratix 10 TX FPGA to sample asignal directly at its RF frequency. READ MORE

5. 4. ANALYSIS, IMPLEMENTATION AND EXPERIMENTAL EVALUATION OF A PHASE SHIFTED PWM CONTROL SYSTEM FOR A MODULAR MULTILEVEL CONVERTER

   University essay from KTH/Elektrisk energiomvandling

   Author : Juan Colmenares; [2011]
   Keywords : ;

   Abstract : Nowadays, it is problematic to connect only one power semiconductor switch directly to the grid due to the high voltage range. In order to solve this difficulty, a new type of power converter has been introduced as a solution in high power applications. READ MORE

6. 5. Linear Time Periodic Analysis of Dc-Dc converter

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Simone Del Favero; [2006]
   Keywords : HTM; Harmonic Transfer Matrix; HTF; Harmonic Transfer Function; LTP; Linear Time Periodic Systems; PWM; Dc-Dc converter; Pulse Width Modulator; subharmonics; chaos; subharmonic estimation; Technology and Engineering;

   Abstract : Aim of this thesis is to analyze Dc-Dc converters by using the techniques of Linear Periodic Time varying (LTP) systems to estimate the amount of subharmonics injected in the load. Dc-Dc converters are used to transform a Dc input to a Dc output of different voltage. In this thesis we study in particular the so called "switch mode" converters. READ MORE
