Abstract –In this paper, proposes an analysis and design of a high efficiency boost-inverter with battery storage in fuel cell. When low-voltage unregulated fuel cell (FC) output is conditioned to generate AC power, two stages are required. The boost-inverter topology that achieves both boosting and inversion functions in a single-stage is used to develop an FC-based energy system which offers ...

This paper proposes a single phase solar based dual mode power inverter system for domestic and industrial use. Which allows the connection of additional energy sources and storage elements to a domestic photovoltaic grid connected system. The systems output port is designed to behave as a power source or sink, which allows the system to behave as power sink or source. It allows the connection ...

Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. This paper presents a novel control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems. The inverter is controlled to perform as a multi-function device by incorporating active power filt...

Grid connected inverters are important building blocks in renewable energy conversion systems. In conventional voltage sourcing grid connected inverters, any mismatch between the synthesized output waveforms of the inverters and the grid voltage will generate large erroneous currents unless a fast current feedback is used. The current control requires rather fast sampling rates and considerable...

-This paper is describing the recently introduced proportional-resonant (PR) controllers and their suitability for grid-connected converters current control. It is shown that the known shortcomings associated with PI controllers like steady-state error for single-phase converters and the need of decoupling for three-phase converters can be alleviated. Additionally, selective harmonic compensati...

In this paper, a grid connected microgrid with multiple inverter-based distributed generators (DGs) is considered. DG in FFC mode regulates the microgrid as a controllable load from the utility point of view as long as its output is within the capacity limit. The transition mode causes a change in frequency of microgrid due to the loss of power transferred between main grid and microgrid. Frequ...
