In this paper, a harmonic elimination and suppression scheme for a dual-inverter-fed open-end winding induction motor drive is presented. Two isolated dc-link sources with voltage ratio of approximately 1 : 0.366 are required for the present drive. These two isolated dc links feeding two inverters to drive the openend winding induction motor eliminate the triplen harmonic currents from the moto...

One promising technology to interface battery packs in electric and hybrid electric vehicles is the multilevel converter. In the work presented here, it is shown how the switching times (angles) in a multilevel inverter can be chosen to achieve a required fundamental voltage and not generate specific higher order harmonics. The method gives a complete solution to the problem in that all possibl...

In this paper, a fully-digital-controlled hybrid series active filter (HSAF) for harmonic elimination and reactive power compensation in single phase systems is presented. The HSAF is composed of two single tuned LC filters and a small-rated active filter. Discrete Fourier transformation is used as the control method. Simulation results using MATLAB program shows the effectiveness of the contro...

This paper presents a comprehensive survey of the current source inverter (CSI)-fed induction motor (IM) drives. It also reviews various control methodologies, selective harmonic elimination techniques and methods for reduction in switching losses in CSI fed IM drives. Authors strongly believe that this survey article shall be very much helpful to the researchers working in the field of CSI fed...

Unlike the trapping of time-harmonic water waves by fixed obstacles, the oscillation of freely floating structures gives rise to a complex nonlinear spectral problem. Still, through a convenient elimination scheme the system simplifies to a linear spectral problem for a self-adjoint operator in a Hilbert space. Under symmetry assumptions on the geometry of the fluid domain, we present condition...

This paper presents a shunt hybrid active power filter application mainly for current harmonic elimination and fixed reactive power compensation. The proposed system consists of a small rated voltage source active power filter and a series of LC passive filter connected to each phase. Besides, no additional switching filter is required for the current ripples. Effectiveness of the system is con...

This paper combines quasi-Z-source into a typical five-level inverter, which includes two dc voltage sources, two quasi-Z-sources and five switching devices. In this structure, the output voltage amplitude is not limited to dc voltage source and it can be increased by quasi-Z-source. Besides, due to nature of Z-source families, this new structure is reliable and higher efficiency. Also, in this...

A New Static Var Generator (SVG), using cascaded full-bridge inverters (FBI) with binary output levels and the parallel connections of two cascaded inverters by means of current sharing reactor in each phases is introduced. The new M-level inverter, where M is 2n+2 - 3, consists of only 2n single-phase full bridges for each phases. The proposed technique not only increases the current capacity ...
