A three phase converter is needed when the "phase" required does not match the "phase" available. In other words, the equipment needs three phase power and only single phase power is available. Phase converters operate by converting single phase power into three phase power. They can also provide split phase voltages from the three phase power source. A three phase converter is used to allow operation of three phase equipment when single phase electrical services are the only power available or vice versa. The majority of the time phase converters are utilized to produce three phase power from single phase power sources as utility companies will associate higher fees for three phase electrical services due to the extra transformers, cabling, and metering required. In this article, we will introduce how to convert single phase to three phase converter.
