Description: Design Guide for Rectifier Use
A transformer s required secondary A.C. voltage varies greatly with the type of rectifier chosen and filter arrangement.
Use the formulas below as a guide based on the D.C. voltage you require and the rectifier/filter chosen. All A.C. voltage references are R.M.S. Don t
forget to take into account losses (not included in this guide), especially diode voltage drop. Leave an adequate safety margin for D.C. regulator voltage
requirements and minimum operating line voltage.
