This article presents the reverse polarity protection for DC/DC converters. It describes the series diode protection, as well as the shunt diode, and P-FET polarity protection circuits. This article ...

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.

As they took him away, Clyde realized that leaving out that protection FET to save $0.35 had been a poor design decision. (Courtesy of Autoevolution) Electronics and automobiles have a long history ...

Different reverse-polarity solutions and their effectiveness at providing car battery front-end protection. How a smart diode controller can provide optimal reverse-battery protection. If the battery ...
