Yesterday’s idea for a Cuk converter synchronous rectifier drive (right) seems to work, according to my use of LTspice. But it needs a rather low value (100Ω) R1 resistor to pull against R2, the 330Ω resistor that turns on (via Q3) the p-channel mosfet represented by the capacitor. As the gate of a mosfet is essentially a …
