CircuitMaker2000 Setup
In analog options only GMIN is changed.
that fixes the time step error from low freq calcs (10hz is a long time)

To make sim run longer edit stop time in transient and fourier analysis setup dialog box...

Hi People

With Gyulas help; I have converted the circuit to solidstate in the sim.
Im searcing for the best cap values and freq, then ill be building this one...

Enjoy

Hi drspark,
thanks for circuitmaker help but ithink power&cop calculation..

total power given circuit is : Power(V1) 
output power =Power(Rin)+Power(Rout)+P.other components.. , so? how can compare input/output power or energy.

like Igor Knitel circuit, with 0.1 ohms/5Watt serial resistor voltage and current
we calculate given power  to circuit.

Hi there Geszin,

If *collect data for; node voltage, supply current, device current and power* is enabled, the simulator will display the power data when you place a probe ontop of the device.

The 10ohm resisters are devices posistioned in series with the battery and at the load point. I use the wave forms calculated as disapated power for those two devices as a measure of the performace.

The power required for switching is not included yet...

Hello,
I just joined this extremely interesting forum. Yersterday I have built and tested your circuit (the one with relays) and it works as you described. Playing with freq and duty cycle you can (quite easily) get battery lamp off and load lamp lit up. I added two 1 Ohm resistors in series with the lamps and felt the different temperature as you did; this further proves that battery current< load current.
However I think we should evaluate the input power as battery current x battery volts  x power factor (because it is not DC); the battery resistor dissipate some power but this is not the input power.
Am I missing something?
Can you calculate the input power as Volts x current in your simulations?

Thanks a lot
