Example sentences

On the other hand for line-frequency rectifier times required for rectifier to switch can be ignored and only significant source of heat is voltage drop on rectification diodes (ie.
So you can make a super low frequency switching power supply using the rectifier itself as the switch.
The four diodes and large capacitor on the right are a full-bridge rectifier to provide 170V DC.
Dart and others (like the iPad recharger [1]) typically convert AC->HV DC (rectifier)->Flyback (at 10's of kHz)->low voltage DC.
So unless you'd doing some crazy electrochemical refining type stuff you'd probably not use a synch rectifier, just not economical.
It was more economical to have a single centralized rectifier than multiple distributed rectifiers.
But changing that to a rectifier + small switcher doesn't seem terribly onerous.
They had a solid state rectifier, so what about a solid state amplifier?
They even light up the rectifier with DC to reduce humming noise...
When you fed an AC current into the track, that circuit in the cars would have acted like a rectifier, turning the AC into poor-quality, high-voltage DC.
After this linear mapping, we apply a nonlinear transform (sigmoid, rectifier, etc).
Quote examples
A lot of the old wall warts are "Type 2", which means transformer, rectifier, reservoir capacitor -- no regulation there at all.
Even if you're simply a "rectifier" (someone who blends and bottles, with no distilling) you need state and local permits as well.
I think the correct term for AC->DC converter like Dart is a "rectifier".
Early 90s EE curricula my experience was more like 50 students came to the first "ohms law" type class and by the time we were talking about rectifier topologies (half-wave, full-wave, bridge, etc) we were down to like 10.
