Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

A couple of scope shots from new 30HS Switch + 30LS Switch + 30 Intercoil switch rig, running a continuously  changing coil current pattern also in rotation.

Very clean sine output with minimal filtering.

Very robust boost recovery on all pulses.


Recovery does reduce input current draw.


Still grossly inefficient.

No load output.

[T-1000]

No load output.

The input power need to be replaced with reactive power on resonant LC tank where coil is inductor for magnetic field induction there. Then you may see something out of ordinary happening when compare input vs output.


Cheers!

Basically the device is a rotary transformer but not an efficient one in my current configuration.


If you take the same coils, in this case 11 connected in series, with the inverse parallel windings (a further 11 coils 180 degrees apart) in place and apply say 30V 50 or 60Hz AC, you get over 85% of input coupled to the rotor coil. This demonstrates that the magnetic circuit is capable of achieving normal transformer efficiencies.


This indicates that I am still way off base in a stepped synthesis of a sine.


This is as much about coupling energy, as it is about not wasting energy. There is way too much power being dissipated as heat in the coils.

The waveform is intended to synthesise a 50 or 60Hz sine in a manner that allows energy recovery.
