Summary

We recently simplified this circuit when we found one of the "legs" was carrying no current at all under simulation. The result is incredibly simple, but still simulates as over-unity. So simple in fact, that our work hardly qualifies as invention, and is more in the category of discovery... discovery of a hidden over-unity property of the simplest of loaded series RLC resonant tank circuits.

Even with Inductor Resistance included, this over-unity proto-circuit, at least as it simulates in CircuitLab, boasts a substantial (near 150%) Coefficient of Performance (COP). COP may normalized some if standardized components with approximate, rounded-off values are used. However, if optimal performance is still desired, variable inductors may be included such that resonances may be "tuned" to the ideal. The best we had with "perfect" resonance, and inductor resistances included, was around 150% COP, using conservative approximations. If in doubt, you are welcome to simulate the circuit yourself, and perform the relatively easy "eyeball" integration of the power-in (Pin) curve to calculate your own figure for COP.

The integration consists primarily of summing the area of triangle-shaped "spikes" which approximate the power curve, separated by large zero areas along the time axis, then dividing by the period of the 60Hz root waveform.

Again, as is, the power input includes momentary power spikes. Conditioning stages need to be added to the input, without affecting over-unity performance.

This work-in-progress is the ideal "proto-circuit" of circuits based on it that use more comprehensive (and realistic) models for inductors, capacitors and diodes, and voltage sources, as well as input power conditioning stages.

Linear components are "conservative," and as has been thought, can't seem to generate power of themselves. Non-linear components, however, are potentially "non-conservative," and if engineered in the proper context, can produce a net power gain in the output.

This circuit is based on the nonlinearity of the diode (D) creating "phantom" voltage or current sources comprised of Fourier series harmonics of a half-wave rectified sine-wave voltage. LC filtering seems to partially block the fundamental harmonic currents from fully manifesting at the load. Further, "full" resonance of a (double-fundamental) frequency paves the way for 2nd harmonic currents, originating in the source combined with diode (D), to reach the load near completely unimpeded.

This "proto-circuit" is a Proof of Concept circuit to justify more research and, potentially, real world implementation. Home-scale units in the 10kW range could be developed for inverter and grid inter-tie connection, and the concept could also likely be scaled-up for large-scale generation on the order of Megawatts.
