Fuzzy Logic-Based Direct Power Control Method for PV Inverter of Grid-Tied AC Microgrid without Phase-Locked Loop

Single-phase H6 Transformerless Inverter with a Simple Boost Converter for Pv-grid Tied Power Systems

Inverters with transformers of conventional type, connected in PV grid-tied generation systems have now being replaced by transformerless inverters due to various reasons such as reduction in size, weight and cost, improvement in efficiency etc. Transformerless inverters cause a number of technical challenges in grid-connected PV systems, among which flow of leakage currents is a major problem....

A New Control Method for Single-Phase Grid-Connected Inverter Using Instantaneous Power Theory

Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...

High Efficiency Grid Tied Interleaved Flyback Micro Inverter with Hybrid Mode for Pv Ac Modules

Boundary Conduction Mode (BCM) and Discontinuous Conduction Mode (DCM) control strategies are widely used for the flyback micro inverter. For the interleaved flyback micro inverter, the dominant losses with heavy load include the conduction loss of the power MOSFETs and diodes and the loss of the transformer while the dominant losses with light load include the gate driving loss, the turn off l...
