Hi ken,

Sounds like the relay is malfunctioning or is not connected correctly???

Best regards

humm, Lamps used are 12 volt 20W.

Hi Ken,

Could you use lamps with lower power like 2-3W? Seems they are too low resistance for the current involved in your circuit, hence probably this is the reason why L2 remains dim. I mean your changing the lamps in your first shown circuit in which L1 slightly glows.

Maybe using 6V lamps also helps (also with types of 2-3W of power first).

You could try increasing NE555 frequency up to 70-80Hz but this depends on whether the relay is able to keep up with the speed...

Hi,
I've checked the connections, did resistance checks on the relays, all hooked up correctly. Tried 100 ohm loads instead of bulbs and the 1st resistor gets hot, the other one cold. This was with inductance shorted.

I can not see how this switching of capacitors from series to parallel and from parellel to series - how it could produce more energy in the second bulb/resistor. once the first set of series caps are charged to 12 volts, and the parallel one are charged to 12 volts; it switches - which would make the new parallel caps now at 6 volts, and the new series caps at 24 volts. Only the 24 volts has 1/4 the energy to what the paralled caps had, (1/2CV^2) and needs more power drawn from the 12 volts DC input to charge up the 6 volt paralleled caps.

I've tried the squarewaves up to 70Hz, and think with a diode across the relay (dumping the back emf - relay chatter) I could make it go higher, except that just make the first bulb glow brighter.

Any thoughts?
Ken

I used 27.9=~28 mH coil. and some times increased voltage 12V to 13-15 V.
bulb light doesnt matter so much, did you get battery current, capasitor voltage?
For self running, self powering operation adding 3. coil to toroid core and with rectif. diods feedback power to capasitors(except relays). I tried but unfortunately wasnt work.

and my friend tested circuit(includes irf510 mosfet) with sim.multisim-7, result :
Volt R2 - 1 Ohms : 12 uVolts..
