We present the physical parameters of three short period close binaries usingthe observed data from Kepler Space Telescope. All of these observations weretaken in a single bandpass (which approximates the Johnson V-band). Our threesystems are KIC 2715417, KIC 6050116 and KIC 6287172. The first system KIC2715417 is considered a semi-detached system with the secondary componentfilling the Roche lobe. The second system KIC 6050116 is an overcontact system,while the third system KIC 6287172 belongs to ellipsoidal variables (ELV) asdeduced from the Roche lobe geometry. For photometric analysis, we used PHOEBEsoftware package which is based on the Wilson-Devinney code (Wilson-Devinney1971). Due to lack of spectroscopic data, the photometric mass ratios aredetermined from the analyses of the light curves using the Q-search method. Theabsolute parameters are determined using three different methods, Harmanec(1988), Maceroni-Van't Veer (1996) and Gazeas-Niarchos (2006).
