Three-level Z-source inverters are recent single-stage topological solutions proposed for buck-boost energy conversion with all favorable advantages of three-level switching retained. Despite their effectiveness in achieving voltage buck-boost conversion, existing three-level Z-source inverters use two impedance networks and two isolated dc sources, which can significantly increase the overall ...

This paper proposes a neuron adaptive harmonic detection algorithm which can adaptively,rapidly and precisely calculate the voltage and current reference signals in presence of the system frequency variation, according to which, a Double Integration Control (DIC) strategy is applied in Unified Power Quality Conditioner (UPQC) as an interface between the hybrid power system and the load.Generall...

This paper presents the design and analysis of a parallel connected inverter configuration of. The configuration consists of parallel connected three-phase dc/ac inverter. Series resistors added to the inverter output to maintain same current in each inverter of the two parallel inverters, and to reduce the circulating current in the parallel inverters to the minimum. High frequency third harmo...

In this paper a new configuration of the single-phase ninelevel voltage source inverter is described. The proposed inverter is based on modified H-bridge converter. To validate the proposed inverter, a low power prototype inverter has been designed and implemented. Instead of sixteen controlled switches as in conventional method, this topology requires only eight switches to obtain nine level o...

To fulfill the challenging demands of the growing grid, new concepts of the inverters are needed. In this project a reduced switch modular inverter design is detailed. A reduced switch modular inverter design is presented for a modern power system which inputs power from both AC and DC Renewable Sources. The modular inverter is the combination of both three phase inverter and three phase invert...
