Capacitors and autotransformers can be used to approximate a three-phase system in a static phase converter, but the voltage and phase angle of the additional phase may only be useful for certain loads.

When three-phase is needed but only single-phase is readily available from the electricity supplier, a phase converter can be used to generate three-phase power from the single phase supply.

With the ability to adjust to changing conditions and maintain voltage balance, a digital phase converter can safely and efficiently operate virtually any type of three-phase equipment or any number of multiple loads.

A "'rotary phase converter "', abbreviated "'RPC "', is an electrical machine that converts power from one polyphase system ( including frequency ) to another, converting through rotary motion.
15.
Power factor correction is a very important consideration when building or choosing an RPC . This is desirable because an RPC that has power factor correction will consume less current from the single-phase service supplying power to the phase converter and its loads.
16.
The locomotives carried a four-pole rotating phase converter feeding a single traction motor of the polyphase induction type at 600 to 1, 100 V . The number of poles on the 2, 500 hp motor could be changed using slip rings to run at one of four synchronous speeds.
