Boost converter
SummaryCircuit analysisOverviewHistoryApplicationsSee alsoFurther readingExternal links
The key principle that drives the boost converter is the tendency of an inductor to resist changes in current by either increasing or decreasing the energy stored in the inductor''s magnetic field. In a boost converter, the output voltage is always higher than the input voltage. A schematic of a boost power stage is shown in Figure 1.
Understanding the Operation of a Boost Converter
The diode permits current to flow from the inductor to the capacitor, but not vice versa. In short, a boost converter stores energy in an inductor''s magnetic field, then transfers that energy to a capacitor in such a
