New Hybrid Cascaded Multilevel Inverter
This paper proposes a single-phase five-level inverter with a modified pulse width-modulated (PWM)control scheme. The modified pulse width-modulation technique is developed to reduce switching loss.Also, the proposed multilevel inverter can reduce the requirement of power switches compared to aconventional cascaded multilevel inverter. The modes of operation, control signals, and operatingprinc...
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...
متن کاملCascaded Multilevel Inverter for Induction Motor Drive
In this paper presents a symmetrical five level cascaded inverter topology for Induction motor drive. It can continuously works at lower power stage. For this symmetrical circuit, when the number of level is increased, the voltage and power will also get increased. For reducing harmonics the Sinusoidal PWM method is used. The multilevel inverter gives the output to drive the three phase Inducti...
متن کاملNew Cascaded Multilevel Inverter With Reduced Power Electronic Components
In this paper, a new structure for cascade multilevel inverter is presented which consists of a series connection of several sub-multilevel units. Each sub-multilevel unit comprises of eight unidirectional switches, two bidirectional switches, and six DC voltage sources. For the proposed cascade topology, two algorithms are presented to produce all possible levels at the output voltage waveform...
متن کاملHarmonic Reduction in Cascaded Multilevel Inverter
This paper presents method of selecting switching angles of a cascaded multilevel inverter so as to produce required fundamental voltage along with improved staircase waveform in terms of harmonics. Cascaded multilevel inverter uses number of DC sources, for k sources number of levels will be 2k+1 and leads to k number of non-linear equations to be solved. Many approaches can be made regarding ...
