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 ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

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.

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...

Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards under the hood and in the cabin. The three major sources of electrical ...
