Three-phase voltage source inverters (VSIs) with output $ LC$ filter are preferred topologies to provide and frequency support for islanded ac microgrids. This article proposes a finite-set quasi-sliding model predictive control (FS-QSM...

The poor quality of voltage and current of a conventional inverter fed induction machine is due to the presence of harmonics and hence there is significant level of energy losses. The nine level inverter is used to reduce the harmonics. The inverters with a large number of steps can generate high quality voltage waveforms. The concept of multilevel inverters, introduced about 20 years ago entai...

This paper develops a flexible power regulation and limitation strategy of voltage source inverters (VSIs) under unbalanced grid faults. When the classical theory is used faults, oscillations current distortions are inevitable. In proposed strategy, extended introduced to compute feedbacks together with theory. Based on combination theory, can achieve sinusoidal provision between three common t...

Ambipolar perovskite field-effect transistors and inverters with balanced mobilities are demonstrated. Thin-film field-effect-transistor-like inverters are developed, and a maximum gain of 23 in the first quadrant for VDD = 80 V is obtained.

A novel Z-source three-level inverter based on coupled inductors is proposed. The two inductors in traditional Z-source impedance network are replaced by two coupled inductors. The operating principle is described and the equations of boost factor and voltage stresses are deduced. Comparisons are made with other Z-source three-level inverters, especially the multicell switched inductor Z-source...
