1. Voltage sourced converters generally produce lower intensity harmonics than line commutated converters. 2. Now let us consider integrals over anti-commutating variables. 3. They are commutated direct frequency converters that are synchronised by a supply line. 4. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. 5. This minimum delay is called the circuit commutated turn off time ( " t" 6. As the speed increases, the inductance of the rotor means that the ideal commutating point changes. 7. Electronically commutated ( EC ) motors are electric motors powered by rectified from AC within the casing. 8. Commutated electric motors, such as universal motors, will run at reduced speed or reduced torque.9. This is one of the lowest ESCR values ever achieved with a line-commutated HVDC converter. 10. In recent years, quiet, electronically commutated motors with increased energy efficiency have been finding use.
