This entry level seminar will provide a practical introduction to the design and testing of power converters. After some material covering the basics of power converters, this presentation will go step by step through the design process of two common converter topologies: a buck converter and a flyback converter. Each detailed design example will cover the motivating application, design parameters, component selection, control loop compensation, circuit board layout, and hardware testing/results. The target audience of this crash course seminar is those with little to no power electronics design experience.
