Recent years have seen some progress in the studies of the central engine of active galactic nuclei (AGN). On the observational side, past space missions such as HEAO-A, Einstein and EXOSAT have brought some considerable progress in the observations of X-ray spectra and time variabilities of AGN. More significant progress is expected in the immediate future due to the current and future space missions such as IUE, GINGA, the Hubble Space Telescope, ASTRO-D, ROSAT, and AXAF. Therefore, it would be important to continue parallel theoretical studies. In this report composite models are presented which naturally explain the observed continuum radiation from seyferts and radio-quiet quasars. Our aim is to explore the central engine of AGN. This class of AGN is selected because it is generally considered to give the most direct information on the central power-house.
