AUXILIARY POWER SUPPLY ? BASED ON PHOTOVOLTAIC ENERGY

Taking into account that power generation is totally changing right now, also providing state of the art net services like net reliability for example need to be discussed again. This paper introduces a new auxiliary power supply based on a combination of a converter, generator and photovoltaic generator, allowing the support of uninterruptible power supply. Depending on the demanded power the system can run in an idle mode that supports net services like compen-sating reactive power. In case of a net collapse is also offers a short term boost condition to stabilize the supply without starting the conventional generator. This all is achieved by introducing a new combined converter, which offers a cheap realization by a applying a new modulation method. For state of the art auxiliary power supplies the new modulation model also can be updated to the existing hardware to improve these systems.
