I have to rectify an AC voltage of 14.5Vac (+10/-15%) at nominally 50 or 60Hz.
Currently I am using 4 x dual Schottky diodes (common cathode), in a bridge configuration.
I am using very low Vf diodes with a combined 70A If(avg). In practice, with the current heatsink,
long term average currents above 50A raise the heatsink to temperatures above 100C
(25C ambient).
I would like to build a full MOSFET H-Bridge instead.
Can the LM5050 and/or LM5051 be used to turn 4 banks of MOSFETs into 4 x ideal diodes?
I envision that each MOSFET will be paralleled.
Assume I have all LM5050s (and/or LM5051s) separately powered from a voltage source of 20V,
derived independently from the same ac power, but with a bridge made with relatively low current,
low reverse leakage current, and very low Vf schottky diodes. [with sufficient capacitance that the
droop between half cycles is less than 100mV - smoothing cap of 5 x 1000uF]
