Review of power electronic concepts of hybrid power source

In this paper, power supply unit based on the Engine-Generator Set (EGS) will be discussed. The recent trends lead to the use of more autonomous power sources to satisfy the maximum energy yield. These power units can be considered as comparatively sophisticated system, consisting of mechanical part, electromechanical energy conversion part, power electronics and control (feed-back) part. These systems usually request a power buffer with battery and bi-directional dc-dc converter. Two aspects will be considered, namely power electronics converter concept with central boost converter design. This paper also briefly shows experimental verification of these modern power sources.
