12-18V DC automatic polarity selector schematic

Closed Posted 6 years ago Paid on delivery
Closed Paid on delivery

Need to develop the 12-24V DC automatic polarity selector/switcher schematic, to automagically switch the polarity of the input Square wave signal (4 channels), to the requested polarity.

For example if the INPUT signal polarity is reversed, it will be automatically reversed back to the "normal" polarity so the device will be powered by correct polarity.

Please note that because target PCB is quite small, so a simple "relay method" is not an option because of the big size.

Design must be compact very, yet withstand 18-24V 3A work for up to 8hours in a row, without overheating.

Hi, I would recommend a simple bridge rectifier. It is the same used for transforming AC to DC signals. The choice of the diodes depend on how much voltage drop you can afford (1.2V at the cheapest solution). More
