This paper presents the modeling and simulation of a proton exchange membrane fuel cell (PEMFC) generation system for off-grid and on-grid operation and configuration. A fuel cell DG system consists of a fuel cell power plant, a DC/DC converter and a DC/AC inverter. The dynamic model for fuel cell array and its power electronic interfacing are presented also a multi-input single output (MISO) D...

In this paper, a series Z-source inverter based on switched inductors cell is proposed for the first time. This inverter is able to increase the voltage gain in comparison to the conventional Z–source inverters in additon to solve the ST (shoot-through) state’s problems. In this inverter, the value of voltage gain is increased by increasing the number of used diodes and inductors in the switche...

This article is an introduction of a new topology of current source inverter (CSI) which can be alternatively implemented in low/medium power applications. This configuration is organized from series connected sub-multilevel inverters blocks. The basis of the recommended multilevel topology is the connections of many cell units in a decent scheme with the help of H-bridge inverter. The suggeste...

This paper presents the implementation of Single Phase 7 level Multilevel DC link (MLDCL) Inverter with Half Bridge Cell topology. For N level inverter, (N-1)/2 half bridge cells are required with the same number of voltage sources. In this inverter topology, 3 Half Bridge Cells are used along with 3 voltage sources, each have 100V DC. These half bridges are connected in series to form a Multil...

Integration of fuel cell stack with an inverter is complex in nature. A number of factors have to be taken into account in designing the inverter as well as during the integration. One of these factors is ripple current which could affect the life of the fuel cell stack if there is fuel and/or oxidant starvation. In this paper an inverter topology is investigated which significantly reduces or ...
