Harmonic Elimination in Multilevel Converters
A method is presented to compute the switching angles in a multilevel converter so as to produce the required fundamental voltage while at the same time not generate higher order harmonics. Using a fundamental switching scheme, previous work has shown that this is possible only for specific ranges of the modulation index. Here it is shown for a three DC source multilevel inverter that, by modif...
متن کاملSelective Harmonic Elimination with Reduced Switch Topology in Multilevel Inverter
A generalized formulation of Selective Harmonic Elimination (SHE) PWM for Multilevel Inverter is recently formulated in literature which can eliminate a large number of lower order harmonics. Various methods for calculating the firing angles for SHE PWM are known and still research in this area is ongoing. This paper presents a MATLAB based approach for modeling and simulation method suitable f...

A method is presented to compute the switching angles in a multilevel converter so as to produce the required fundamental voltage while at the same time not generate higher order harmonics. Previous work has shown that the transcendental equations characterizing the harmonic content can be converted to polynomial equations which are then solved using the method of resultants from elimination th...

selective harmonic elimination (she) is a powerful modulation scheme aims to find the required switching angles in order to eliminate the number of undesired harmonics. she is a complicated problem which consists of several nonlinear equations which have multiple local minima. in order to eliminate the higher number of undesired harmonics and as a result reducing the total harmonic distortion (...
متن کاملNeural Network Controller for Harmonic Elimination in Multilevel Inverter
Uninterruptible power supplies (UPSs) are emergency power sources which have wide spread application in critical equipments, such as computers, automated process controllers, and hospital instruments. With the rapid growth in the use of high-efficiency power converters, more and more electrical loads are nonlinear and generate harmonics. It is a big challenge for a UPS to maintain a high-qualit...
