Microgrids represent a new and flexible form of electrical networks. This form is based on the use of Distributed Generators which are connected to a microgrid through Voltage Source Inverters (VSI). In this paper, we propose a nonlinear controller that allows the regulation of the output voltage and frequency of a VSI. The system consists of a VSI and an LC filter associated to a coupling indu...

Currently, a two-level voltage source inverter (2L-VSI) is regarded as the cornerstone of modern industrial applications. However, control VSIs challenging task due to their nonlinear and time-varying nature. This paper proposes employing fractional-order controller (FOC) improve performance model-free predictive (MFPC) 2L-VSI in uninterruptible power supply (UPS) In conventional MFPC based on ...

This paper presents a Modified control method for Space Vector Modulated (SVM) Z Source inverters. Proposed algorithm provides a modified voltage vector with single stage controller having one degree of freedom wherein traditional controllers have two degrees of freedom. Through this method of control, the full utilization of the dc link input voltage and keeping the lowest voltage stress acros...
