Abstract

A switched-mode power supply (switching-mode power supply or SMPS) is an electronic Power supply incorporates a switching regulator in order to be highly efficient in the conversion of electrical power. In SMPS using PWM chip, It requires hyperbolic curve of nonlinear nature of Input voltage & on time for smooth working. The desired hyperbolic curve of nonlinear nature cannot be obtained using the existing PWM chip. So sometimes it over compensates & sometimes it under compensates. This causes error in the output voltage. In this paper SMPS with linear PWM strategy is introduced.
