How does a boost converter work?

Question

I recently came across boost converters while exploring ways to step up voltage from a low-power source. Can someone explain how they work, the key components involved, and why they are commonly used in such applications?

Sebastian · Answer

A boost converter steps up voltage using an inductor, switch, diode, and capacitor. The switch stores energy in the inductor, and when it opens, the inductor raises the voltage, which is then directed to the output capacitor.

These converters are efficient, compact, and commonly used in battery-powered devices and applications requiring higher voltage from a low power source.
