Hi!
What do you think about this Sax battery technology?
Can be used for audio purposes? e.g. battery powered amplifiers?

The cascade H-bridge increases the voltage output whereas what we need in audio is mostly an increased current capacity, as higher power systems are all multi-speaker, often wired in parallel.
However, a parallel poly-phase multilevel modulation method with similar benefits (as cascade HB) was proposed by Karsten Neilsen at the AES 102nd Convention, Munich in 1997, with the title:
"Parallel Phase Shifted Carrier Pulse Width Modulation (PSCPWM) - A novel approach to Switching Power Amplifier Design"
Hope that helps.

The SAX Power Home works with 230Vac/16A. For me that would be sufficient. 🙂
The question is the quality of the AC. sinus, noise etc.

Dear Tyimo, my response was based on the assumption that you were proposing the CHB technique for a battery powered switching amplifier.
Are you looking to make 50Hz power at mains voltage?

But why an inverter when you could run your amplifiers directly (using batteries)? That's an extra power conversion stage which would impact efficiency, which I think is important, given the fact you're running from batteries...
For example, if you live in a place where you are not on the mains or do not want to be connected to a noisy mains.
But since this place is expected to have batteries, you could directly run the amplifiers using the batteries, instead of running them from an inverter that runs on batteries. And you wouldn't be needing the mains (or the inverter), as you're directly running from batteries. Hope that helps.
Well, if you're particular about an inverter, then I do not see any reason why you need to be concerned about waveform quality, as most mains-powered amplifiers run using AC-DC converters. Besides, the battery circuit being separate from the mains, would inherently have much lower noise.
However, for motor loads, sinusoidal waveform purity matters a lot, as a circular flux trajectory is necessary for quiet and reliable operation.
