Moderní topologie víceúrovňových napěťových střídačů s redukovaným počtem spínacích prvků

Abstract

This thesis is focused on modern topologies of multilevel inverters with reduced number of switches. In addition to these inverters are also discussed the classical topologies of multilevel inverters and their control methods in theoretical part of the thesis. Modern topologies of inverters controlled with subharmonic PWM are built in the Matlab/Simulink program and described in practical part of the thesis. Simulations are focused especially on analyzes of THD and total power losses.
