The present research work aims to study the large signal stability of two parallel-connected voltage-source inverters operating with resistive droop control through bifurcation analysis. This minimal setup can be considered as a prototype of a small islanded ac microgrid studying where droop control acts as a synchronization scheme between inverter...

This paper proposes an isolated modular single–phase inverter for high–input voltage applications. The topology is composed of conventional and modular full–bridge inverters with series–connected inputs and magnetically–connected outputs. All input bus capacitors are connected in series and thus the dc voltage is divided among the inverter modules....

In this paper, a new full–bridge modular inverter topology for open–end split winding induction motor drive is presented. All bus capacitor related to a specific phase is connected in series to reach the desired voltage level required in high power and high input-voltage applications requirements. The number of inverters per phase is related to the...

This paper proposes an isolated bidirectional dc-dc converter, based on the duality between Zeta and SEPIC converters. Active-clamping is used to recycle the energy trapped in the transformer leakage inductance and to protect the power semiconductors against over-voltages. Theoretical analysis, modulation strategy and experimental results are inclu...

This work presents mathematical analysis, simulations and experimental results of the parallel connection of DAB converters. The gyrator technique is used to model the DAB converter and to determine a simple equivalent circuit. As the DAB converter is a natural gyrator, the paralleling can be easily done, and the control logic is simplified. A simp...

This article shows simulation and experimental results of the dc microgrids interconnected with the power grid. By having different voltage levels the connection between microgrids and utility grid requires a converter responsible for this link. The TAB (Triple Active Bridge) converter was chosen for the connections between microgrids and utility g...

This paper deals with the current control of the bidirectional Zeta-Sepic DC-DC converter. By means of the state average method, the transfer function representing the ratio of the input inductor current to the duty-cycle is deducted and val-idated by simulation. A digital controller is proposed, analyzed, designed and simulated. The proposed digit...

This paper presents a three-phase grid-connected photovoltaic generation system with unity power factor for any situation of solar radiation. The modelling of the PWM inverter and a control strategy using dq0 transformation are proposed. The system operates as an active filter capable of compensate harmonic components and reactive power, generated...

This paper presents a three-phase grid-connected photovoltaic system with unity power factor capable to work under any situation of solar radiation. When the solar radiation is high, the power flux is from the photovoltaic array to the grid, and when it is low, the grid ensures the energy to provide the loads connected to the system. The PWM modula...
