Active rectification, or synchronous rectification, is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT). Whereas normal semiconductor diodes have a roughly fixed voltage drop … See more The constant voltage drop of a standard p-n junction diode is typically between 0.7 V and 1.7 V, causing significant power loss in the diode. Electric power depends on current and voltage: the power loss rises proportional to both … See more Replacing a diode with an actively controlled switching element such as a MOSFET is the heart of active rectification. MOSFETs have a … See more See H-bridge. See more A MOSFET actively controlled to act as a rectifier—actively turned on to allow current in one direction but actively turned off to block current … See more • T. Grossen, E. Menzel, J.J.R.
