The unit is a UPS system
1.) The UPS unit , takes the AC 120 outlet and converts it to DC and then converts it back to 120 VAC
2.) The inputs and outputs are isolated because of the higher frequency switcher circuit
No sure how the high frequency switcher circuit works? do you? I can't even see the high frequency on my oscilloscope because the frequency are so high, it just looks very messy on my oscilloscope
3.) There is a phase shift between the UPS outputs and the AC Mains input
4.) The Phase Lock circuit , locks the UPS output AC 120 with the AC mains input 120 VAC
why does the input and output of an UPS system need to be in phase?
To try and display the UPS output at the same time as the AC mains input, to see the phase difference, requires more than two channels
How do you set up the oscilloscope to measure the UPS output at the same time as the AC mains input?
