Modelování a simulace napěťového střídače se Sigma-Delta modulací

Abstract

The aim of this master thesis is to create a modulation strategy using principles of sigma-delta modulation. In the theoretical part of the thesis are described principles and characteristics of chosen standard control methods of voltage inverters. Subsequently, there is in detail examined principle of sigma-delta modulation. In the simulation part of the thesis is assembled simulation model with specified configuration of voltage inverter which uses sigma-delta modulation. At the conclusion a comparison of data obtained from simulation with standard control methods of voltage inverters is performed.
