Adaptable inverter for injection of fuel cell and photovoltaic power

Due to environmental conditions it is becoming more and more important to apply renewable energies and efficient technologies. For power injection of photovoltaic and fuel cell energy an inverter is needed. The presented modular and flexible prototype works with different energy sources such as photovoltaic, fuel cell and battery. It is possible to adjust active and reactive power as well as current shape separately within limits to improve power quality. The power electronics works very well and is able to convert 20 to 80 VDC into 110 VAC/60 Hz or 230 VAC/50 Hz with a high flexibility and efficiency.
