Optocoupler Circuits, Working, Characteristics, Interfacing

Last Updated on March 15, 2025 by Swagatam 51 Comments

opto coupler internal view

OPTOCOUPLERS OR OPTOISOLATORS are devices that enable efficient transmission of DC signal and other data across two circuit stages, and also simultaneously maintain an excellent level of electrical isolation between them. Optocouplers become specifically useful where an electrical signal is required to be sent across two circuit stages, but with an extreme degree of electrical […]

High Current Voltage Doubler Circuit

Last Updated on March 12, 2025 by Swagatam 18 Comments

highcurrentvoltagedoublercircuit

In this post I have explained a voltage high current doubler circuit which will almost double the voltage that’s been applied at the input (up to 15V max), and also it becomes specifically useful since it allows higher current loads to be used at the output, in the order 10 amps. Since the voltage doubler […]
