Active rectifier circuits uses power transistors (MOSFET or BJT) or operational amplifiers to achieve better rectification than diodes. Below is a circuit schematic of an active rectifier drawn in Proteus professional. The rectifier is driven by sinusoidal signal of 100Hz.


By connecting an oscilloscope at the output we can view the output signal waveform as shown.


A better rectification is obtained using LM355 op-amp. This is shown below.






The output is below.




Another improved version of rectifier that uses the 741 op-amp is shown below. It uses two diodes at the output of the op-amp.


The output signal waveform from this rectifier is shown below.
