Abstract:
This research project deals with the development of a solid, intelligent converter with a good value. The energy of fuel cells or other low-voltage energy-sources (40 to 80 VDC) is feeded decentral into the public net (230 VAC/50 Hz or 110 VAC/60 Hz). Because of the requirements of the serial product (e.g. low price, reliability, range of use) a prototype of a converter with high frequency transformer was built. The latest electronic devices and a digital signal processor as central controller have been applied to achieve high efficiency and flexible power injection. It is possible to obtain improvements of the local voltage quality and stability by adjusting active and reactive power as well as power factor and current shape.

Abstract:
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.
