Build a Low Forward Drop Rectifier Wiring diagram Schematic
A TMOS power FET, Ql, and an LM393 comparator provide a high-efficiency rectifier schema. When V,. exceeds V,, Ul`s output becomes high and Ql conducts. Conversely, when VB exceeds V,., the comparator output becomes low and Ql does not conduct.
The forward drop is determined by Ql`s on resistance and current I. The MTH40N05 has an on resistance of 0. 028 !l; for I = 10 A, the forward drop is less than 0.3 V. Typically, the best Schottky diodes do not even begin conducting below a few hundred mV.
