I am aware of various oscillator circuits which have the capabilities of increasing frequency.
I was wondering if a circuit could be designed with ONLY using inductors and capacitors? The frequency must be increased from 60Hz to either 500Hz or 1kHz.

Voltage output = 1kVAC at 500Hz or 1kHz
Load = capacitive and/or inductive

If this is not possible, what is the best oscillator circuit that can be used with high voltage? Is there one I can assemble on my own? Any part numbers?

Thanks for your help in advance!

 

What voltage? Are you talking about line voltage or stepped down with a transformer? What output voltage? Since wave or square wave (other?)? What is this driving - how much power needs to be delivered to the downstream device?

No. Since you plan to use only LC tank circuits and since neither 500 or 1000 is a multiple of 60, harmonic multipliers will not work. You will need to use active circuits like a PLL.

 

With a square wave input possibly. A sharp bandpass filler could extract a harmonic. With a sine wave input, I don’t see how.

Edited to add: And this would be at a severe loss of amplitude.

Any part numbers that would work with high voltage?

I don't think there is a PLL IC that works with your outputvoltage.

How much voltage and current? 20V is high voltage for most ICs.

 

Can't give you a good answer until we know the voltage and current you need.

First Post: outputvoltage 1kVAC

 

I think he expects to use s 1000 VAC 60 Hz supply and passives to supply 1000 VAC 500 Hz power. Ain't going yo happen.

 

What do you plan to do with the 1kV AC @ 500Hz ? What are the tolerances on those figures?

 

Rectify the 1kV and use a H-bridge to create the desired outputvoltage. Not an easy task but i don't think there is an easy solution.

I would like to have capability of having a voltage output ranging between 1 - 10kVAC. The current should not exceed 2A

 

What's wrong with 10kV/2A @ 60Hz?
A 20kW transformer is going to be expensive, even at 500Hz; especially at 10kV

I have voltage sets that go that high. I just need to convert the frequencies.

 

Id be looking at hiring a power engineer with lots of experience with high voltage / high frequency power supples.
