Abstract
This paper deals with an improved power quality multiple output switched mode power supply (SMPS) using two stage DCDC converter. A non-isolated buck-boost DC-DC converter is used as the first stage whereas single ended primary inductance converter (SEPIC) is used in the second stage. The first stage of buck-boost converter is designed in discontinuous conduction mode (DCM) for inherent power factor (PF) correction. Design and simulations of the two stage DC-DC converter with load variations on the SMPS are performed in MATLAB software to demonstrate the effectiveness of the multiple output DC-DC converter to have a stiff voltage regulation and negligible ripple.Keywords: DC-DC converter; Two stage; PFC; THD; Buck-boost converter; SEPIC; SMPS; Power quality
