Design a control circuit to step-up/step-down the voltage either in primary or secondary side of the transformer. The tapping (step-up/step-down) of the transformer must be auto controlled by VB program.For example, suppose if the desire voltage in the secondary of the transformer is 15V, but because of the loss, the voltage might drop to 12V. So, a sensor is used to detect this drop and send the message to VB. VB will process the message and send the reply signal to control circuit so that the voltage will step up (compensated) to 15 V. If the voltage exceeds 15 V, VB has to rectify it also.Can anyone please show me some guidances or circuit diagram of this project? Thank you!!!!
You are very much over-complicating the problem. All you need is to get an 18-volt transformer and design a 15 volt voltage regulator circuit based on it. Radio Shack has lots of books, parts, and resources to get you going. Also, check your local public or college library for electronics books. Have fun!
