Agreed. We are paid to do good but not ridiculous engineering. Leave that for
Hollywood. Or Star Wars (the project, not the movie).
For serious high power (3 kW to Terrawatts), three phase service is the
recommended design. With a simple 6 rectifier bridge, the ripple is down to
4.2% RMS, and with a 12 pulse Delta-Wye connected dual secondary transformer,
1%.
The need for large capacitors is eliminated, and a simple LC or just C filter
is enough. This eliminates the hazardous stored energy that takes a lot of
expensive parts and design care to prevent damage to amplifiers and cables.
