Interesting Oscillator

I decided to make an oscillator, then I decided to make it an AM frequency oscillator, and I ended up with this thing. What kind of oscillator is this and what can it be used for?

Its a "hartly" oscillator. Core is the LCL pi as highpass which will make the 180° phase shift. The BJT in common emitter does also 180° so you get 360° in total.

Yes, I understand how it works, I just didn't know what it was called. This particular version creates high voltages from a lower voltage power supply. What could it be used for?

Its just used as oscillator, what else do you think it can be. The only additional characteristics I can think of is, its very harmonic rich cuz its based on a high pass and not like a collpits on a lowpass to make the 180°

What ? Splitting the inductor creates a high pass.

Right, http://everycircuit.com/circuit/5225898547871744

I'm asking what it could be used for because it uses a low 9V DC to produce a much higher ~60V AC wave. That must have at least some uses. I tried to use it as a simple boost converter but the efficiency was around 10-20%. Maybe you could refine and modify it into a simple reasonable-efficiency boost converter?

Use a peak detector or extent it to a long cascade. But do not expect to much output power. http://everycircuit.com/circuit/5470425296666624

@jason9, he said something, who cares...

I just wanted to see how much efficiency this thing could produce as a boost converter. When you say, "@jason9, he said something, who cares...", are you referring to @selman saying something about high/low pass filters and harmonics and then me making a low pas filter based oscillator to reduce harmonics and you're wondering why I did it. I just wanted to make a circuit.

Check the efficiency and get back.

I wasn't patient enough to let the thing stabilize fully but I measured an efficiency of <1%.
