Greetings everyone! I am back and moving forward. I have closed out two issues based on research I have done over the past year.
* For the AC/DC converter, ON Semiconductor offers the best selection of power factor correction chips that meet our voltage and power output requirements. In fact, the NCP1654 allows for a universal voltage input (85-245VAC input voltage) so that we don't have to change designs based on where we use the UPS.
* For the DC bus, we will be using 48Vdc. This voltage is becoming (or has become) a de-facto standard. It helps with current levels and we can get smart battery packs with a similar voltage level.
The path forward as I see it is as follows:
1. Confirm that we can go from AC to DC and back to AC. Use evaluation boards for this.
2. Separate the AC/DC converter and the DC/AC inverter and use buck and boost circuits to have a 48Vdc bus.
3. Create sensor circuits for Mains, Sens0, and Sens1; confirm that we can read those with forebrain.
4. Further steps as these are accomplished.
Thanks for the patience guys. We are moving forward.
