We can very easily find the step down transformer in our daily life as they are used as full wave rectifier in various charging as well as power sources. 

Also the stepdown transformers has found a great application in measuring a very high voltage as a potential transformer and measuring the high current as a current transformer. 

Feel free to make your own circuit and do share it on DCAClab subreddit. Also check out that how to use the transformer in DCAClab.
