Hi, I have a SMPS PSU in action into my 500W Class D IRS2092 currently, now i am thinking to addon a secondary supply which is 24Vdc battery into the circuit. The target is to switch over battery when the Main AC voltage disconnected and reconnect to AC automatically when AC voltage resume.
I am thinking which is a cheaper, smaller, and higher efficiency solution, should I invert the DC voltage into 220Vac or should i just boost it into 400Vdc similar to the PFC voltage?
Any other smaller footprint mosfet switch that are more suitable for this application? Because I think Relay is too slow to react, and the mechanical switch of Relay is not long lasting.
Hope you guys can enlighten me in this...
