Current-Doubler Rectifier Reduces Ripple Current

Focus:

An alternative output stage for buck-derived power converters, the current-doubler rectifier reduces noise and capacitance values, while simplifying transformer design versus a conventional center-tapped transformer with sceondary-side, full-wave rectification.

What you’ll learn:

• How to cancel the ripple current seen at the output capacitor in a buck-derived power converter
• How to simplify implementation of synchronous rectification
