Abstract

This thesis discusses the design and fabrication of an Isolated Multiple Output DC-DC Converter. Based on the design specifications, a Flyback topology was selected as the suitable type of DC-DC Converter to implement isolated multiple output setup. A total of three outputs, each with 5 V rating, were implemented to simulate multiple output. The primary output was designated to be the well-regulated output while the two other outputs, quasi-regulated. The design methods consist of series of steps that highlights careful selection, construction and configuration of the components for the complex circuitry of the DC-DC Converter. Results of the design phase were presented and implemented into a PCB board for testing. Loads were connected to the outputs to test the fabricated DC-DC Converter. Output waveforms generated from the components of the converter were observed under the oscilloscope and also presented in the study. Load landline regulation tests were used to collect data for the characterization of the converter and to see the effects of the quasi-regulated outputs to the well regulated output. Furthermore, the study encompasses straightforward techniques that might be very useful to inexperienced designers in building a DC-DC Converter. It was concluded that the design methods locally available products used were effective in fabricating an Isolated Multiple Output DC-DC converter.
