This paper presents a grid connected system. Three phase DC-AC inverters used to convert the regulated DC power to AC power suitable for grid connection. Third harmonic injection PWM (THIPWM) was employed to reduce the total harmonic distortion and for maximum use of the voltage source. DSP was used to generate the accurate THIPWM for grid connection, by synchronizing the inverter voltage with the...
This paper presents the design and analysis of a new configuration of parallel connected inverter suitable for distributed generation application. The configuration consists of DC/DC converter and parallel 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...

This paper presents a fuel cell model supplying three-phase DC/AC inverter. Simulink used as interactive tool to model the proposed fuel cell system. The fuel cell output voltage is proportional to the change of the air (oxidant) pressure, the hydrogen (fuel) pressure and the current withdrawn from the fuel cell. Three-phase DC/AC inverter used to supply the AC load. Symmetric space vector pulse width...
