| Abstract: | Construction of CCD camera power supply is analyzed in this paper,that provides camera with a single power out- side.In order to realize a function of multiple DC/DC converter,a solution of system design for a switch regulated power supply combined with linear regulated power supply is proposed.Working two characteristics of regulated power supply are analyzed,one is a switch regulated power supply to be provided with BOOST/BUCK,another is linear.Aiming at the design demands of a whole CCD camera,the perfor... |
