Why use 2 mosfets? Answered
In the circuit, they use 2 mosfets namely q1 and q2.
I was thinking what does q1 do.
I tried simulating the circuit with and without q1 and the result were identical.
Almost all synchronous rectifiers are following this pattern, what could be the purpose of q1?
input and output conditions...
Input: sine wave similar to AC mains (100Vrms 60Hz)
Output: half wave rectified sinewave
Load: 1kOhm resistor
The red curve in the graph represents the voltage in the output
The blue curve in the graph represents the voltage of a 1 ohm resistor in the input (for current reading purposes)
