Hello Helpers I am new in electronics can anyone suggest the best circuit to convert 100V to 12v my circuit needs 12v 1A current and I have a Electric forklift that gives 95v output which I need to convert to 12v for my circuit

There is a reasonable choice of buck regulators for 100V DC input

I was going to recommend the MeanWell products as well, but @LowQCab got there first.
Before you buy anything, is does your forklift have a 96V (48 cell) lead-acid battery?
If so, the voltage on equalisation charge might be as high as 2.7V per cell (129.6V).
Probably best to make sure your device gets disconnected when the battery is put on charge.

 

I could provide a Schematic for a DIY project,
but it costs almost 4X as much over just buying one ready-made from DigiKey.

Meanwell PSUs are good as IanO suggest and they work with low input voltages too.

Can you share the schematic it will be helpful for me

Thankyou and can it work on my scenario ?

 

If You have to ask that question,
then You should purchase a commercially manufactured Converter,
like the one that I previously provided a link to.

Hello I have this converter and it converts 70V Dc to 12V DC
https://electrobes.com/product/dc-36v-72v-to-dc-12v-20a-dc-dc-converter-adapter/

can I use a series of zener diodes for the input to drop 100-70V=30V for my converter input please also mentioned the zener diode which is useful in this case or anything else

I want to convert 100VDC to 70VDC for this converter input

 

Zener-Diodes would be a poor choice.

At 1-Amp of Current,
that would mean that the Zener-Diodes would have to dissipate ~30-Watts of HEAT.

Purchase a SMPS that is specifically designed to do the job.
( Like the one I provided a Link to )

If Zener Diodes were practical, the manufacturers of SMPS's would be out of business.
