Inductive dividers split AC input according to inductance:

A Brushless AC electric motor is an electric motor driven by an AC electrical input, which lacks any form of commutator or slip ring.

At the time when the AC input reaches its negative pole the leftmost diode is allowing current to flow from the ground into the first capacitor, filling it up.

If the SMPS has an AC input, then the first stage is to convert the input to DC.

A SMPS designed for AC input can usually be run from a DC supply, because the DC would pass through the rectifier unchanged.

The Combo Preamp combines a separate AC input and line level input onto a single amphenol connector.

Rectifier circuits that have a higher pulse number have reduced harmonic content in the AC input current and reduced ripple in the DC output voltage.

These must typically store enough energy at this high voltage to power the load during the zero crossings of the AC input.

For example, for a three-phase AC input, a half-wave rectifier consists of three diodes, but a full-wave bridge rectifier consists of six diodes.

Power supplies, often referred to as "switching power supplies", use switcher technology to convert the AC input to lower DC voltages.
