How do I transform a power supply to other voltage value? Answered
I need a 9.0 V AC 1.0 A power supply but despite I have a lot of power supplies around, no one has this values. The most I have are 12 V DC
I suppose there must be some method to lower or rise the voltage of a power supply to meet the required voltage. Also, the resulting power supply must be AC (I also have a 20V AC power supply if this is easier than converting from DC to AC)
Please, tell me what do I have to do.
