Hep please

Can anyone tell me who created the first dual power supply and what are they commonly used for today?

Thankyou

 

Who created the first dual power supply, I think that is not marked in the History. Dual power supply is used for the supply of the operational Amplifiers.

 

hi nirvana,

any circuit configuration that needs a negative supply will use a dual supply just like what "dragan" has cited. audio power amps also used that.

 

Cant say who created them but They are also extensively used in the audio field. Instument amplifiers, PAs and the like.

 

i dont think there is a certain person who took credit for the dual power supply...ill c wut i can find on google but so far have found nothin...if this is for school and u find the answer id b glad to kno it...thx l8er

 

To be a smarty. God. other than that ask these guys, they might know.
