hello every one.
I have designed an Oscillator using 741 op-amp. it can supply 20mA maximum But i have to have 3A for my circuit purpose. so please suggest me the current Amplifier that i can design to have 3A at the output.
thanks
i am adding my Oscillator circuit.
And yes Eric, you are right.The load is a motor.which require 2.4A. i am thinking that i must amplifier to 3A.
thanks
Isn't there anyone who can help me?
@ Eric
yes it is written on the motor that i requires these things to run in a fine mood.
and what about this Transistor? can i just simply bias it like we bias the normal common emitter Amplifier to give me 3A?
hi
OK. i got the idea that how drive this power Amplifier. and i think it is very easy. look at the attachment what i am think is correct?
@ Eric
Sorry! Eric i didn't understand.what do you want to ask me.
yeah! you are absolutely right. i only have a truck battery of full size (i don't know what we would name it ).
what i was think is that, that first i'll convert D.c into A.c with 300Hz and then amplify the current and then after having enough current i'll step-up the voltages.
What do you suggest? is it possible?
