Hello I am going to built DC Current transformer for measuring high DC currents . In this first design part is Oscillator . The Oscillator output is coming as 20Khz (which i needed frequency ) and the output voltage 3V(R.M.S) and current 2.96pA(rms pico amps). But i need minimum output current is 1A (r.m.s) and the output power is 5W (so my output voltage must become to 5V). I heared that this can bedone by the power amnlifiers(Audio amplifiers ). in that amplifiers i want to use TDA2030 or LM1875. So friends can you give the ciruit diagram or simulation file. I am ateching the Oscillator simulation file....
Thanks in Advance
