How can you convert household AC electrical power 1 phase to 3 phase?

Answer:
For low-power appliances you can buy an electronic power inverter which produces 3-phase outputs from a 1-phase (single phase) service.

Such inverters are not cheap to buy so you must decide if it is best to buy an equivalent appliance that runs on 1-phase instead of trying to use a 3-phase appliance on a 1-phase supply using a power inverter.

Note: For mains power any 1-phase service is usually obtained by using just one phase of a 3-phase service that comes in overhead or underground cables from the generating station.

The power company typically supplies a given neighborhood with 3-phase service and distributes it as separate 1-phase services, one phase per street or group of streets, so that each house in each street gets its 1-phase power.

If the owner requires it, it is usually possible to pay the power company to provide a 3-phase service into a house or any other type of property - such as an engineering workshop, vehicle repair garage, etc. - that may need to have a 3-phase service for machinery or other equipment.
