I have a simple universal SMPS of 12V 1A. The problem is I have three independent AC power sources. One is the main power, the other one is the backup from an inverter and the other one is from a generator. Both phase lines provide 230VAC 50Hz.
I want to power a microcontroller-based board that will use that 12V 1A SMPS. How can I use single SMPS and connect the three power sources across the SMPS?
My condition is that the SMPS should not turn off if one or two of the power sources fails. Also, I cant use transformers as it will fluctuate if the input AC voltage drops significantly.
Please note - I can modify the SMPS. It is based on power integration Driver IC.
