Are those two AC bridges equal. If not, how do they behave differently?
I do not understand if the following circuits are equal or if there's any difference in how they behave.
I assumed that it depends on the current, but then I have seen both used with AC and DC, so ...

Must this switch be turned on and off periodically?
Imagine that the AC1-2 is 170VAC at 150kHz~.
I simply want to turn the MOSFETs on, and let the AC flow through a inductive-capacitive load.
1) If I can turn the MOSFETs on to saturation by applying ...

Why don't more devices incorporate full-wave rectifiers as reverse polarity protection?
Recently, I was introduced to the idea of using a full-wave rectifier, in order to protect against reverse polarity damage in DC devices.
I hadn't even considered using a rectifier in an already DC ...
