Question though?
Why are you after low-conduction drop? is it to try to get as much voltage from the supply
or is it to improve efficiency - ie less voltdrop => less power lossed in the switches.
If it is the efficiency you have to factor in the gate-drives of the switches.
answer
yes , yes, true ...
maybe i'm not looking for a sync rectifier at all..
all i want is to be able to convert my 20V p-p generator output to DC, without loosing 12.8 W in the process..the frequency of the generator is (varible up to 100HZ)
**AC test:**
Voc =20Vp-p
(Loaded) is with a 1 ohm resistor
VLoaded =12Vp-p
average power:
(VmIm/2)= 6*6/2= 36/2 = 18W
**DC Test..:**
(a bridge rectifier setup) was used ,and a 3000uF cap across the output to smooth the wave..
VLoaded = 4V
I = 1300 mA (measured)
power 5.2W
