Abstract: This paper deals with two stage SMPS system in which forward converter is used as step down converter and modified boost converter is used to increase the real power share in apparent power of source as well as to reduce the higher frequency currents in source current. To get rid of kilo-hertz currents in load, it is preferred to make the terminal capacitor voltage ripple free with the use of CLCS. Boost converter is adjusted to get rid of high stresses over a switch. The settling time of terminal voltage was adjusted to a fraction of second without affecting the output DC’s smoothness.
Keywords: Boost converter, Forward converter (FC), Power factor (PF), and Switch mode power supply (SMPS)
