cop > 1

[Inquorate]

having trouble with this site on my mobile phone, best luck so far with opera mini 4.

@Gyula - I've tried caps but the tension in them tries to equalize instantly and transistors and optos etc kept dying.

I think if you don't see OU it will be because of capacitor losses. I'd be interested to see the difference in joules in the 'charge' cap with simple pulse and with a pulsed coil and recovery diode.

Unfortunately I'm swamped at the moment, I have a one month old boy and it'll be a while before I get back in the lab.

If you take a look at the links i posted, you will see that the answer to both your questions is yes.

Thanks for your interest.

Ok, I am always in the mood for an experiment.   I will post results and we discuss findings.

salutes,

ps: congratualtions for your newborn child, young father

good luck, i'll try to be on hand with any questions you may have.

@All,

I have measured the COP by charging a super capacitor.
Still a long way to go to reach COP>1 in my circuit.

Groundloop.

have you tried supercaps with the circuit i posted?

@Inquorate,

No, but I will try it. Did you use a 555 circuit to pulse the transistor?
Do you have information on pulse frequency and duty cycle?

Is the attached circuit the one you did use?
