If you need to convert AC-AC(Up convert or down convert) you can use transformers.

Primary winding 1 yana AC(alternating current) 1 amplitude 1 vary wena nisa 1n emit wena magnetic flux 1th vary wenawa. Ethakota secondary coil 1n kepena magnetic flux 1th vary wenwawa. A varying magnetic flux creates a EMF(Electromotive force) in the secondary...... This is called mutual induction, now if we connect a load to the secondary, a current will flow.

Me current 1 apita ona viyata hadagannae(or voltage) coilswala thiyena turns gana wenas karala(affecting the EMF generated in effect)....
