Abstract
This research work is on designing a PWM based SMPS instead of using conventional pulse generating pre-programmed chips. All the topologies of SMPS are studied and their ranges of application are analyzed as well. Two SMPS designs have been proposed. One of them is using analogue switching method by 555 Timer while the other one using microcontroller for PWM generation and feedback control. Firstly, single phase SMPS has been designed using microcontroller and load-end feedback. The single phase layout has been modified to introduce a Three Phase SMPS and the results are observed. Later on The three phase SMPS using microcontroller has been implemented and the difference between the software simulation and practical results have been analysed. The designed Three Phase SMPS gives a value of 5.003V for 5V output, 9.012V for 9V output and 12.677V for the unregulated 12V output.
