Precision Rectifier Op Amp Circuit: How does it work?

A precision Rectifier active circuit is analyzed in this video that examines how this op amp diode circuit is working and how to find its input-output Voltage Transfer Characteristics or VTC. For more examples see • Electrical Engineering...
This active rectifying circuit is designed with two operational amplifiers and two diodes with negligible forward bias voltage. Both op amps are properly biased with negative feedbacks and hence virtual short is applicable to both op amps. The second op amp is wired as a buffer. Depending on the value of the input voltage, the first op amp is operating either as a buffer or as an inverting amplifier with superposition. For more examples see

As practical applications of the Rectifier Circuits, computer and mobile power adaptors and AC to DC converters use rectifiers to convert AC alternating voltage to a 12v or 5 volt DC supply that charges computer or mobile device.
I hope these circuit examples are helpful.
