Parallel converter can significantly increase the capacity of the converter and improve the power quality of AC side, but the circulation which can lead to high switching loss and even damage the devices will easily exist in the direct parallel converters. In this paper, the average model of parallel interleaved inverters system to analyze the circulation current is shown, and the cross current...

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...

-Simplified active NPC (ANPC) inverters enable a substantially increased output power and an improved performance at zero speed for high-power electrical drives. This paper analyzes the operation of Simplified ANPC inverters under device failure conditions, and proposes the fault-tolerant strategies to enable continuous operating of the inverters and drive systems under single device openand sh...

Inverters with reduced number of switches have been proposed in the literature to improve the capability of cost reduction, total inverters size and switching losses of dc/ac inverter topologies. In addition, they have a lower probability of damaging the semi-conductor switches as well as lower commonmode currents. This paper proposes new designs for inverters with reduced number of switches. F...

This paper studies microgrids where loads are supplied by parallel connected inverters controlled by decentralized active power/voltage frequency and reactive power/voltage magnitude droop control laws. The implementation of droop control laws for sharing of power between inverters has been known to present stability problems particularly for large values of active power/voltage frequency droop...
