Abstract
High headroom in a magamp postregulator increases circuit losses, including power transistor losses, saturable reactor core loss, and freewheeling diode snubber loss. Higher headroom also requires the use of higher voltage diodes. The authors describe common causes for large headroom requirement and discuss various techniques to reduce it
