How To Clean Up Modified Sine Wave

For any of these solutions (auto-transformer, RC networks, etc) it would be nice to see some sort of before-and-after performance measure. For example, oscilloscope pictures of distorted waveforms before the solution is practical, and cleaned upwardly waveforms after the solution is practical, if you can provide whatever. This would give u.s. incentive to spend time and $$$ on that solution, or non.

Regarding the autotransformer, Variac etc make some units, seem to be optimized for ability line conditioning, also capable of adjusting the output voltage.

Without going too deep into theory, the MSW smoothing effect seems to exist the low-pass inductor/winding characteristic, which here may be able to filter our strong MSW harmonics and noise across lx hz.

The fact that there is no isolation between input and output doesn't seem to affair, because I don't have any isolation to brainstorm with.

A failure in the winding insulation should just have bear on on the inverter, and would not endanger the load because I am using the auto-transformer as slight stride-up and not step-down.

Also good benefit, if I have several taps in the secondary (or continuously variable secondary), and so I can use it to regulate upward the RMS output voltage to the desired value with no-load, or make it load-dependent.

I thing I don't yet fully empathize, there may exist a phase difference between the voltage and the current at the auto-transformer output that powers the load (but like in whatsoever inductor with some resistance in the winding). This degraded ability factor would cause reactive power to develop in the auto-transformer winding, which would exist sent back to the inverter and not to the load. How much power loss would there be, and what this would do to the inverter, I don't know.
Seems like we are dealing here with a case where the ability source itself, and not the load, is causing the reactive power component. Maybe some capacitive ability cistron correction would exist needed at the auto-transformer output to have care of this, and brand this solution usable Whatsoever comments?

Regarding the RC networks, I assume this would be R=five ohm and C=0.7 uF elements connected in series. Then I am not exactly sure, two RC series circuits would be connected from each of the hot and neutral outputs of the MSW inverter to ground, or one RC serial excursion connected between the hot and the neutral?
Which style is it?
