ABSTRACT
This chapter examines the various practical techniques that have not been covered in previous chapters for designing switch-mode power supplies. It describes the design of the input stage, the selection of the converter topology, the design of inductors, the design of transformers, the design of output circuits, the design of controller circuits, and the minimization of electromagnetic interference. The chapter outlines the role of computer-aided design (CAD) tools in the design of such circuits. It discusses a mains-operated off-line switching regulator. Two kinds of interference are generated by switch-mode power supplies: conducted interference and radiated interference. Precautions should be taken to minimize both kinds of interference during the design stage of the switch-mode power supply. The source of interference may also be totally enclosed within a grounded metal box to prevent the escape of the electric field.
