Sure...

What shall we tranform it into?

Oh, wait... do you want to make 1VDC from something else?

What about losses?

Well, they are gone... converted to heat, or sound, or vibration, or... lost.

Losses from what? If you can tell us more about what you are doing you will probably get some good advice.

What? Did you really think that we'd get a realistic set of conditions? If the OP actually knew everything needed to design a transformer, they'd design a transformer themselves.

Yeah, you're probably right...

It does appear that the art and skill of question-asking is another subject that has been dropped from curricula around the world.

I usually allow a little elbow room for a language problem. Here at my work, there are many English speakers who, asking for my help, I must drill with the 'Twenty Questions' routine to arrive at what they are really after. Sad, this.

You can design a transformer to change any AC voltage from one voltage to another. Fabricating a transformer to efficiently transform AC power from one arbitrary voltage to any other voltage can be more difficult than just designing it but it can also be done.

Radio frequency Transformers in radio equipment work at less than 1 microvolt and up to thousands of volts, depending on purpose....telephony/"broadband" modem transfos work at around 1V...Current transformers for power frequencies work up to 10s of 1000s of amperes or at microamps in instrument isolating/coupling....etc

If you want to design a transfo you need...

  1. Frequency range and waveform.
  2. Input voltage or current range and load values.
  3. Input/output ratio and accuracy requirements.
  4. Ambient conditions [temperature/pressure/humidity etc
  5. Maybe size/weight/efficiency restraints.
  6. Maybe limits on pick-up from surrounding electrostatic/magnetic fields [e.g. microphone application].

and so on...
