This is excellent but in typical low voltage scenarios (5V or lower) the 600mV diode voltage drop becomes very significant. Simple diode half wave rectification works fine at 100V, but at 3.3V it breaks down.
- xxs 11mo agoat that point (and in general) you'd like to use Schottky ones. MOSFETs are an option for low extra efficiency.
- tiniuclx 11mo agoYou can also build a rectifier with no voltage drop using an op-amp with some diodes in the feedback loop. But that might be considered cheating :)
- jotux 11mo agoFor low voltage diodes you can use mosfets to get ultra low voltage drop, or just buy dedicated "ideal diode" components that are specifically for that: https://www.analog.com/media/en/technical-documentation/data-sheets/max40203.pdf https://www.analog.com/media/en/technical-documentation/data...
