    Please help me by Recreating same 230v to 12v 2amp PCB same BOM compents (for low cost effective Making) for PCB images given for reference.

    Do you have the permission of the intellectual property rights holder to reproduce that design?

    Since all eight coils are nominally the same you could sim the combination like this: The contents of a dotted rectangle represent four coils in series. Rload is arbitrary here.

    It would be if the bottom of that set/array of coils had a connection to ground. But the reactance due to all those coil inductances forms a voltage divider with the load they're driving, so the voltage across the load is lower than you're hoping for. Edit: As the coil voltages are being only...

    You had inductances, correctly added in series with the voltage sources (coils), in the asc file you posted previously. In case you've over-written it I'm attaching it here.

    Top left corner ? Your sim shows 128Hz. Your power coil array needs a ground connection. The sim needs a run time of more than 1 sec.

    I can't believe your L5 coil inductance is only a few nanoHenries!

    There are inductance calculators online.

    Yes. Your voltage sources also have significant inductance, which should be taken into account in the sim.

    The "-" is because V7 is sourcing power. Most of the available power is being dissipated by L1. Now give your voltage sources and transformer coils some realistic internal resistance.

    Where are nodes N002 and N005?

    Your sim coils and voltage sources have zero resistance, so give totally unrealistic resultIs. Ctrl+ left-click in the title of a waveform plot will give a drop-down box with average and rms values of a waveform.

    The turns ratio is 4 : 23, so the inductance ratio for LTspice will be the square of that, i.e. 16 : 529. See post #717 for the power per coil. Multiply by 8. Current depends on load, which will vary with motor type and speed.

    Use Alt+left-click on a coil to plot its power dissipation.

    That should give you 40V, with the current capability of two coils.

    The negative nodes of your voltage sources in the post #698 sim are floating, so no surprise the output tends to zero.

    If all the coils are passed by a N pole at the same time then their outputs are in phase. You could wire them all in parallel and have 10V output at 8 times the current capability of a single coil, or you could wire them all in series and have 80V output with the current capability of just a...

    If the coils are all in phase then why do you show V1-V4 with 90* phase shifts in the sim?
