:: The mains input bridge rectifier in every PSU I've seen is just a normal 4 diode bridge, it's at worst a 2% loss. The output from the transformer probably has synchronous rectification due to the much lower voltage, but not an H-bridge, instead a center-tapped transformer winding and 2 MOSFETs. The only H-bridge in a PSU is the inverter.

I interpreted Randall imagining "inversion" as "reciprocal" (or maybe the inversion of a function) rather than physically turning something upside-down, since mathematical inversion is typically reversible...
