Most of the electronic circuits require a DC power supply to operate. There are many designs and topologies covering different properties and specifications for DC power supplies. The voltage and current range and accuracy, power capacity and quality, failure protections, isolations, robustness and reliability, power efficiency, size and ease of usage are some of the most important characteristics of power supplies. A DC power supply with the parameters given in the following sections is designed and realized for the fulfillment of the Master of Science thesis. The criteria for making decisions on the design parameters were range, isolations and ease of use. The range is proposed to be 30VDC and 5A output. The isolation is realized both between the mains and the device and between the device and PC that, when connected, controls it. For the ease of use, a 4x4 keypad to enter data and a 2x20 character LCD to monitor data are used.
