A ripple current minimisation based single phase PWM inverter
This paper is aimed at improving the output voltage waveform of a single phase PWM inverter. Two approaches is proposed, the first approach is based on selected harmonic elimination (SHE) of order up to 7th harmonic, for minimising harmonic distortion and modulating amplitude of the fundamental component of the output voltage waveform. For the first time, the Levenberg– Marquardt algorithm (LMA) ...

A predictive algorithm for minimising dead–time distortions in sine–wave VSI with L–C output filter
In many applications, single–phase sine–wave inverters are operated with low–pass filters at the output to deliver a low–distortion sinusoidal voltage to the load. In such cases, it is essential that the output be as close to a sinusoid as possible. However, conventional bridge–type inverters, which must be operated with some dead time, suffer from dead–time distortion problems. This effect ...

Comparative study on various unipolar PWM strategies for single phase five-level cascaded inverter
A single phase cascaded inverter consisting of two full bridges creates a five-level AC output voltage. Due to switch combination redundancies, there are certain degrees of freedom to generate the five-level AC output voltage. This paper presents the different types of unipolar pulse width modulation (PWM) strategies for the chosen inverter. The effectiveness of the developed strategies are ...

Analysis and design of controlled capacitor charging type power frequency inverter
This paper presents the performance of the capacitor charging type inverters. The inverter uses the voltage and current feedback and produces a desired voltage at the output by suitably charging/discharging a capacitor. An inductor is connected in series to limit the charging/discharging current. Both single and three phase inverters are considered. A small signal analysis is presented to ...

PSO-based solutions to selective harmonic elimination in stand-alone photovoltaic inverters
This paper presents accurate particle swarm optimisation (PSO) based-solutions for nonlinear equations of selective harmonic elimination technique to be used in single-phase stand-alone photovoltaic inverters. The proposed PSO-based method computes efficiently the required switching angles of inverter control signals to eliminate low order harmonics up to the 15th from the inverter voltage ...

A novel feed-forward and feed-back control of a VSI for variable speed wind-driven PM alternators
This paper brings out an improved control strategy for an inverter employed to integrate a 3-kW wind-driven permanent-magnet synchronous generator (PMSG) to the utility network. The proposed controller features a feed-back control for enhanced current tracking performance and a feed-forward control for power tracking with varying wind-speeds. The harmonic content of the current fed to the grid is ...

Controlling the number of on-grid multiple photovoltaic inverters to improve their conversion efficiency
Two experimental PV-grid connected systems of 8.8 kWp and 36 kWp rating have been designed, installed and interfaced with Abu Dhabi utility grid. The PV arrays of both systems are interfaced with the grid via single phase grid-tied inverters. The inverters are installed in three separate groups that each injects 50 Hz electricity into one phase of the utility grid at the 0.4 kV level. The main ...
