I have been following these youtube tutorials on active rectification to learn more about the topic.
I simulated the final full wave active rectification circuit, in ltspice, with 4 mosfets and a mosfet driven by an op amp to prevent reverse current. However I am noticing that this design starts to fail for lower AC amplitudes.
35V active rectification:
Edit: Improved diagram from Audioguru
Take for example when the input voltage amplitude is 10V instead of 35V. there is a larger voltage drop and (some) distortion on the waveform. Why is this? Is Full wave active rectification for lower voltages achievable?
