I am duped on how power supplies work as I am not an electrical engineer but rather a hobbyist or a DIYer.
I am looking for cooling solutions and discovered the inverter technology.
If I understood it correctly, the compressor is run by DC, running at variable speed for whatever the system needs. If I want to assemble a phase-change system, using a DC compressor, and I have an AC power source (residential) and convert it using an AC-DC converter, I do not know how much electricity I am consuming.
This is what I am thinking, and these are just examples for simplification: suppose that I use a switched-mode power supply, rated at 10 A, and connect it to 220 V AC - the power consumed is 2,200 W. If I connect it to a load, DC, for example it outputs 12 V, and the load uses 5 A, so that is equal to 60W...
My question is, how much electricity am I consuming, and consequently have to pay for? Is it 2,200W or 60W?
