Understanding the Basics of DC-DC Conversion

Figure 1: DC-DC converters can be isolated or non-isolated

When Allesandro Volta made a battery out of copper and zinc disks and brine-soaked cardboard, it was a novelty and the low power DC produced had few practical applications. As electricity became better understood and it was discovered that rotating magnets could induce AC current in wires, the world of power ge
