hello every body.
Can a sinusoid waveform oscillator circuit witch is designed with an op amp (LM10 for inst.) be amplified and be used as a 200 V, 1 A , 20khz, power supply ?
thnx.

 

Don't confuse oscillators with amplifiers. The oscillator generates the waveform/frequency, the amplifier delivers the power.

 

ok. i mean that a high frequency low power sinusoid oscillator as an input to a common emitter and then emitter follower amplifiers can be used as a high frequency high power , power supply?

 

A sweeping statement, but without a schematic I'll just say no.

 

The question is as much whether the amplifier you are imagining could deliver such power, as what type of oscillator should be used.

Using an LM10 is pretty hopeless though. On page 7 of this datasheet, you will see that its performance at 20kHz is quite dismal. http://www.national.com/ds/LM/LM10.pdf
