No, there is not. Three phase ,or generally speaking multiphase, circuits are available only for AC (alternating current) systems, because there is no phase shift in DC (direct current) systems. This is because DC power is not sinusoidal (current flows in one direction).
Single-phase means you have a simple AC supply on two wires, usually a live and neutral, as supplied to the average house throughout the world. Single-phase also includes a split-phase system where you have for example a 240 v supply with a centre-tap neutral giving two separate 120 v supplies. The alternative is three-phase, which can be on three wires or it can include a 4th neutral wire. It is used for transmission of power in bulk because it uses wire efficiently over long distances.
There actually is no such thing as 2 phase. You either have single phase (As most/all residential services), or three phase (primarily in commercial/industrial). When a normal three phase motor 'loses a phase' (blown fuses, open winding, bad contactor, etc...) if it continues to operate, it is considered 'single phasing'. While such operation is typically only briefly. (They usually don't run long) While it probably will not operate very long, the motor would over heat, and loose speed rapidly, and they will sometimes make noise. If you need to operate a three phase motor on residential service, you will need a 'three phase converter' (some people call them 'inverter's) to electronically convert single phase power into three phase, but they are usually only practical for smaller three phase motors.
Single phase alters from positive to negative at 50 (50hz) or 60 (60hz) times per minute. While in dc it does not vary but stays at a constant positive phase.
120 volt single phase rectifies to about 96 volt DC
No!The concept of three phase alternating electricity refers to the relational phase differential of three alternating current single phase sine waves, each displaced 120 degrees of phase angle from the other.Addetion:still the is a three wire DC transmission system.usually DC transmission used for several resone but the most know one is when the transmission line is longer than 600 km
The choice of single or three phase depends on the available supply. But a three-phase full wave rectifier provides 6 pulses of DC per cycle, while a single-phase full-wave rectifier provides only two. That makes the output DC easier to smooth.
By using a three-phase rectifier.
Single-phase means you have a simple AC supply on two wires, usually a live and neutral, as supplied to the average house throughout the world. Single-phase also includes a split-phase system where you have for example a 240 v supply with a centre-tap neutral giving two separate 120 v supplies.

The Single and Three phase refer to Alternating Current electrical power supply outlet system and the corresponding equipment requirements. The single phase system is generally used thepower requirements are low or moderate as for household applications , while the Three phase supply system is used for High power industrial applications. Thenumbers of phases refer to Alternating Current Supply lines which are delivering the power or the sytem requirement of the equipment for operation. Thus a single phase supply cannot operate a three phase equipment or vice versa. However a ThreePhase supply can be used individually as Three different Single Phase supply systems In case of Three Phase systems the electrical supply waveforms are such that at any given instant there is a 120 degree phase difference between any two supply lines , which also results in higher magnitude of supply voltage than the corresponding single phase supply. Now refering to the inverter which is nothing but a device to convert the electrical supply from one source or magnitude ( typically DC from a Battery Bank ) to the required form and Magnitude. Thus it simply generates the equivalent electrical supply either as Singleor Three Phase , which ideally will be the same as available available from the wall outlet
For a three-phase, four-wire, system, single-phase loads can be connected between any pair of line conductors. For a three-phase, four-wire, system, single-phase loads can be connected between any pair of line conductors, or between any line conductor and the neutral conductor. The choice depends on the voltage requirements of the load.
To change the connection of a single-phase line to a three-phase line for a DC motor, typically you would need to use a phase converter or a variable frequency drive (VFD) to convert the power supply. This will allow you to provide the necessary three-phase power to the DC motor for it to operate efficiently and safely. It's important to consult with an electrician or engineer to ensure the proper conversion is done based on the motor specifications.
in ac supply both positive and negative cycles contain in single phase the fuse only required for supply side but in dc supply positive and negative seperated by two terminals so we provide two fuses.
Three phase is ac

It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
The AC supply would have to be changed to DC supply.. This would be done with the use of a rectifier. It would be done usually with a full wave rectifier.
Single phase rectifiers are suitable to power loads of up to only about 15 kW. For higher power demands, three phase rectifiers are preferred for the following reasons: Higher dc voltage, better TUF, better input power factor, less ripple content in the output current - therefore giving better load performance and a smaller size of filter circuit parameters because of the higher ripple frequency.
