چکیده
The parallel operation of inverters has many benefits, such as modularity and redundancy. However, the connection produces circulating currents that may result in malfunctions system. In this work, a control technique for elimination low-frequency components grid-connected is presented. proposed structure contains n − 1 zero-sequence loops, with being number connected parallel. Simulation experimental results have been carried out on prototype composed two 5 kW obtained by considering following mismatches between both inverters: inductance values grid filters, unbalance delivered power, use different modulation techniques.

Simplified control method for parallel-connected DC/AC inverters
The parallel operation of several low-capacity inverters is better than a singular highcapacity inverter owing to the advantages of better extensibility and reliability. A simplified control method for parallel-connected inverters is proposed, which can balance the current distribution among the parallel-connected inverters with no interconnected communication lines. To verify the performance o...
متن کاملVoltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control
Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent. This controller is used in a double loop structure including an inner current loop and oute...
متن کاملPll for Single Phase Grid Connected Inverters
In grid connected applications the synchronization of output signals of the converters to be connected with grid parameters frequency and phase is of great importance. Different methods based on Fourier transforms, zero-crossing detection, Kalman filters, phase-locked loops (PLL) and others are used for this synchronization. This paper presents a new PLL for synchronization of the output curren...
متن کاملA Lyapunov Approach to Control Design for Grid-connected Inverters
This paper develops a Lyapunov approach to control design for grid connected inverter. The control objective is to track a reference current which is proportional to the fundamental harmonic of the grid voltage. By using the internal model principle, the grid voltage and the reference current are described as the outputs of an autonomous linear oscillatory system. The state of this oscillatory ...
متن کاملCirculating Current Reduction Strategy for Parallel-Connected Inverters Based IPT Systems
Multiple inverters connected in parallel is a promising method to upgrade the power capacity of inductive power transfer (IPT) systems. Due to a slight unbalance of the control signals, the inner resistances of the inverters and other uncertainties, circulating currents exist among the parallel units which reduce the reliability of IPT systems. Firstly, the series-parallel resonant tank is empl...
