Figure 1 A series diode protects systems from reverse polarity but wastes power in diode losses. Figure 2 You can use a bridge rectifier so that your system works no matter what the input polarity is.

This application note describes the diode selection process and snubber design for high voltage inverting flyback converter for subscriber-line interface card (SLIC) applications. Critical diode ...

[Afroman’s] latest video shows you how to add reverse voltage protection with minimal power loss. At some point, one of your electronic concoctions will turn out to be very useful. You want to make ...

A special control IC that emulates a “smart diode” along with an external MOSFET allows positive inputs and prevents negative inputs for automotive and industrial applications. This new IC replaces ...
