phase converter การใช้

• The principle was as follows : A rotating phase converter fed the stators of the motors.
• In one type of digital phase converter the input rectifier consists of IGBTs in series with inductors.
• A rotary phase converter is a three-phase motor with special starting arrangements and power factor correction that produces balanced three-phase voltages.
• After realising that, he also provided the means to build such a rail network by inventing a rotary phase converter suitable for locomotive usage.
• Variable-frequency drives and Digital phase converters use power electronic devices to synthesize a balanced three-phase supply from single-phase input power.
• In rural areas farmers who wish to use three-phase motors may install a phase converter if only a single-phase supply is available.
• The successor of the Kand?V40 locomotives, the Class V55 proved to be a failure and M罺 decided to purchase no more phase converter engines.
• "' Castle Manor Academy "'( formerly Castle Manor Business and Enterprise College ) is a secondary phase converter academy school in Haverhill, Suffolk.
• He created an electric machine called a synchronous phase converter, which was a single-phase synchronous motor and a three-phase synchronous generator with common stator and rotor.
• Between the output voltage midpoint ( 0 ) and the mains midpoint ( M ) the common mode voltage u0M appears, as is characteristic in three-phase converter systems.
• 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.
• 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.
• 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.
