Retrofitting the D.C. power supply for ITM machine laboratory / Roha Mat Arif

Power supplies are inseparable parts of electronic appliances and equipment. Most direct current (dc) power supplies in use today are powered from an alternating current (ac) source rated at 240Volts and 50 Hertz. This project focuses on the hardware development of a d.c. power supply for a three machine experimental set. The objective of the project is to create a new solid state power supply to replace the 50kVA d.c. generator set in the general machine laboratory. The noise from the d.c. generator set is affecting the smooth running of other experiments. This supply unit is developed to supply 220V, 13A d.c. output continuously. The d.c. power supply was constructed and tested. The design construction and testing of this power supply are presented in this thesis
