This article proposes a model-based voltage quality analysis and optimization method for
post-fault reconfigured N-level Neutral Point Clamped (NPC) inverter. It is found that the …

Grid-connected inverters need to reduce current harmonics as much as possible. After
introducing the input signal's fundamental and main harmonic quadrature components, a …

Hybrid grid-connected inverter (GCI), also called reconfigurable GCI or shunt-series-
switched GCI, can be connected in shunt or series to the grid to improve power quality of the …

The present study aims to improve the power quality of an ac-ac direct matrix converter
using hybrid filters. In this paper, a direct matrix converter (without a dc capacitor) is …

This paper proposes a multi-level inverter (MLI) which has two or more unequal DC voltage
source with lesser number of components. The proposed MLI composed of many basic DC …

This article examines the performance of a single-phase PWM inverter equipped with a PI
and PID controller. The research aims to decrease Total Harmonic Distortion (THD) in case …

The growth of especially small-scale distributed generation connected to the low voltage
electricity grid has brought significant benefits to customers, but has brought new challenges …

Currently, most photovoltaic (PV) sources are connected to the grid. This research discusses
single-phase on-grid PV inverters. A two-stage inverter which consisted of a boost-type DC …

This study proposes a half-bridge dc-bus spilt-capacitor voltage balancing circuit based on
DΣ control. The circuit can be designed according to the load requirements and be …

To avoid the cost of extra high-precision sensing circuit, single injected current feedback
control scheme has been developed to complete both current regulation and active damping …
