In this study, a new switched mode power supply (SMPS) for personal computers (PCs) with improved power quality and enhanced output voltage regulation is designed, modelled and implemented in the hardware. The normally used diode converter at the front end of any SMPS is eliminated in the present configuration by making use of two non‐isolated power factor corrected (PFC) converters at the front end in a back to back manner. This is followed by an isolated dc–dc converter which yields multiple dc voltages required in the PCs. The front end converter is designed in discontinuous conduction mode with a single control loop to achieve both voltage control and PFC. A fair comparison between the conventional SMPS and the proposed SMPS is made to demonstrate the effectiveness of the proposed configuration which is verified by simulation results and corroborated with experimental results.
