摘要：Many industrial, sciencetific, medical, communication and defence equipments require 32 or 48 volt power suppply. These equipments can be operated in a fixed placed as well as in a mobile unit. Unfortunately, many power supply, especially in a mobile unit, available only in 12 volts. These 12 volt power may come from car battery or solar cell. In this research, a 12 volt DC to 48 volt DC converter is designed, implemented and tested. The power supply is designed as a swithcing mode power supply (SMPS) with feedbcak regulator for efficiency and operasional flexibility. This way, the output voltage can be adjusted by the user to meet their need. The performance of the power supply is obtained by varying the input voltage and varying the output voltage. The power supply is also tested by applying the converter using car battery as its input and loading the power supply. Test results show that the power supply could deliver power from 26.6 to 55 volt DC for input voltage of 9.8 to 12 volt. For output of 48 volt, the converter yields an efficiency of 85% with ripple voltage of 50 milli volt peak to peak
