Amit , Dr. Manoj Kumar. "Design And Implementation Of Multiple Output Switch Mode Power Supply". International Journal of Engineering Trends and Technology (IJETT). V4(10):4540-4545 Oct 2013. ISSN:2231-5381. published by seventh sense research group.


In this paper, the design of multiple output power supply is presented. An Embedded system requires different voltage levels for its proper functioning because the components used in any embedded system required different voltage levels as per their specifications, so this paper proposed a power supply that includes +15V, -15V, +5V, -5V, +3.3V, +5V Isolated voltage levels. The input for this power supply is 48V DC which is available at all telecom sites. This power supply is capable of providing approximate 40W output power with 80% efficiency. The power supply design topology selected for this paper is flyback converter because flyback converter is a better option as compare to other topologies for low power design and for generating multiple output voltage levels. This power supply is designed by low cost and highly efficient discrete components and the paper also describes the criteria of choosing these components. This supply designed here can be used for almost all applications in telecom embedded products due to its versatile range of constant output voltage levels.
