Abstract :
DC-DC converters are the heart of any switched mode power supply (SMPS) system. Rather than using multiple number of DC-DC converters for regulating voltage of each of the outputs in a multi-output SMPS, the reliability and cost-effectiveness can be improved if a single DC-DC converter is used and viable control technique is employed to regulate the voltages effectively. This paper deals with such a multi-output SMPS of 175W rating, typically used in a personal computers (PCs), using forward boost converter. An effort is made to improve the input power quality also at the utility interface by employing average current control mode. The effect of load variation and input supply variation on SMPS is studied to demonstrate the performance and effectiveness of this converter in regulating the outputs in the wide range of mains voltage.
