Active Rectifier Circuits: Convert Alternating Current to Direct ...
2020年10月4日 — In this video we will discuss the active rectifier, which is an op-amp-based circuit that uses a normal diode in conjunction with negative feedback to rectify signals without generating a significant amplitude difference between …
Active rectification - Wikipedia
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). [1]

Active Rectifier Circuits: What You Need to Know
2020年5月18日 — An active rectifier directs rectification patterns of a diode. The circuit uses negative feedback and amplification to avoid voltages that aren't compatible with the diode's ability to conduct current.
† An active rectifier can be combined with a capacitor to store the true input voltage. † The first amplifier is set up as an ideal diode. † Positive voltage through the diode is stored at the capacitor.
Activity: Active Rectifiers [Analog Devices Wiki]
Active rectification, also often referred to as Synchronous rectification, means switching the FET device on and off at an appropriate point in the AC waveform according to the polarity, so it acts as a rectifier conducting current only in the desired direction.
Conventional input protection circuits use either a Schottky diode or a P-Channel MOSFET based circuit to provide reverse battery protection. Schottky diode rectifies the AC ripple superimposed on the battery voltage effectively. The challenge with Schottky diode is the high power dissipation due to high forward voltage drop across it.

2018年1月1日 — The very first active rectifier was developed by using a single-switch in a boost topology. With the advantage of operating in different conduction mode, simplicity and resulting in an almost sinusoidal input current this topology has well adopted in different applications.
ADALM2000 Activity: Active Rectifiers | Analog Devices
The objective of this lab activity is to examine active rectifier circuits. Specifically, one that combines an op amp, a low threshold P-channel MOSFET, and feedback to synthesize a one-way current valve or rectifier with less forward drop than a conventional PN junction diode.

A full-wave rectifier is a circuit that converts both half-cycles of the AC voltage waveform to an unbroken series of voltage pulses of the same polarity. The resulting DC delivered to the load doesn’t “pulsate” as much.
