the hybrid inverter fed induction
motor drive has ensured the high power factor of about 0.95 which nearly a unity power factor and also improves the performance of the system.
The standard
motor drive analyzer software provides either full-spectrum (no harmonic filter applied) or fundamental-only harmonic filters.
The higher SINAD enables more accurate current and voltage measurement, which improves the performance of
motor drives by reducing torque ripple on the motor shaft.
Under the normal condition, the R-FSPM
motor drive operates in the conventional BLAC operation mode.
The hydraulic pump test rig has an electric
motor drive with computer-controlled speed, as well as the capability to handle up to 250 bar of pressure and lO,O00rpm.
Motor drive frequency converters can reduce energy use in those applications up to 70 percent.
New space vector PWM strategy for a low cost three phase inverter fed induction
motor drive is given in [5].
