Don't believe that APS is a commonly understood technical term related to power supply. It's not even listed with a respective meaning on the Wikipedia disambiguation page. https://en.wikipedia.org/wiki/APS

Please clarify what you are talking about.

hello again,
sorry for the unclear post .the thing is in our country when you say APS everyone knows what we are talking about.
i will try explaining myself
aps=is a dc to ac inverter it could be square or sine wave.in this case it is a sine wave . it is called an aps because when electricity is present a relay automatically turns on and the user will be supplied from source.
my question is how to transfer this to a line interactive inverter.
