Hello, i need your help.
I need to amplify a low current (100mA) voltage signal to a higher current without changing the voltage. The voltage output operates a machine that requires 5A to work. The voltage is approximately 500V A.C
Kindly help me with a circuit that can enable me archive this or something close to this.
Thank you!

Mother nature (and the energy conservation law of physics) does not let you generate 2500W from a 1250W source.
You need a source of at least 2500W.

You're not understanding the relationship between current and voltage. It is a reciprocal relationship.* If one goes up, the other must go down. And vice version. If you are intending to maintain voltage a specific level, while increasing current ten times what it is, you need to draw this extra current from somewhere other than the 502VAC you're working from, because your 502VAC @ 100mA is max.

Law of Conservation of Energy.

*You may think you see example that defy this, but that would be because the output is being -regulated- by a change in one or the other to provide what you're seeing.
