It was commonly used to create a completely balanced three-wire 120/240-volt DC electrical supply.

When connected to a DC supply, the rectifier stage of the power supply performed no active function.

DC-only equipment would only run from a DC supply and included no rectifier stage.

Fluorescent lamps can run directly from a DC supply of sufficient voltage to strike an arc.

The primary winding of the flyback transformer is driven by a switch from a DC supply (usually a transistor).

Each pair thus operates in common mode as one side of the DC supply, so two pairs are required to complete the circuit.

Usually running from a DC supply, when combined with a planetary gearbox can offer accuracies less than 8 arc-minutes (/ of a degree).

For DC supply, the ideal is the voltage not varying from a prescribed level.

To operate the coil continuously, the DC supply current must be broken repeatedly to create the magnetic field changes needed for induction.

The DC supply for traction motors is made available through a rectifier circuit.
