Hi to all!!!
I need to generate 1V and 100 Amp. for heating application from 24V dc source....how can I generate it??
Can high frequency transformer(around 40Khz) helps??
Do anyone know this kind of transformer??
You wind it yourself, or have one custom wound.
Bear in mind the secondary winding needs to be VERY thick.
ya, I know it is difficult to get, but you mentioned for thick winding (I guess for high currrent), do you think size can be compact like this shown in the figure if it is made???
What do you need 1V at 100A for?
This seems like a very unusually low voltage.
I can't see it being very efficient, perhaps 50% at best; the problem is resistive losses on the secondary side, you'll loose 10% efficiency for every 1mÙ..
If your supply is limited to 5A then you have a problem because I doubt you'll be able to get 83.33% efficiency at such a low voltage out.
Isn't the output of the heat gun more likely to be AC than DC?
You guys are over complicating things.
Just use a group of Ni Cad or NiMh cells in parallel.
Under load they will pull down to around 1.05 volts and can easily source 10 -15 amps per cell with out overheating.
Strip a cordless drill battery pack and rearrange the cells to work as a 1.2 volt high current source.
Just what is this weird secret device and just what does it have to heat? What is your power supply and what size does the whole device have to fit into??
Heating Element: Kanthal plate
power supply: 24V 5-6Amp.
Device: It is a device which is used to heat the samples(sand samples) to particular temp. for particular time , and record the data.. it's scientific instrument , used in research ...
We are trying to replace bulky AC transformer with high frequency DC if possible with small size,,,
