Full bridge Phase-shifted full bridge Lack of space here prevents full coverage. However, there are two great sources you can explore to evaluate your topology choices: Power Topolgies Quick Reference Guide : These nine pages provide a quick refresher on the most common switching power-supply topologies. More details are available in the page Power Topologies Handbook. Circuit explanations and design recommendations are based upon requirements. Figure 1 shows the simplified circuits for each. The buck format steps down the input voltage while the boost steps it up. The other three can do either. If you need some isolation, transformers can be employed. Topologies that will incorporate them in the design are flyback, clamp forward, push-pull, half bridge, or full bridge. As for switching frequency, it usually comes down to the best estimate based on your application. Today, typical switching frequencies range from about kHz to several megahertz. Low frequencies are generally better for higher-power applications requiring best efficiency. Higher frequencies make filtering easier with smaller capacitors and inductors, and can lead to reductions in both size and cost. Also be sure to consider the impact of the fundamental and harmonics on other equipment nearby.
