N4L Power Measurement Tutorial 2 (Short) PWM Motor Drive Efficiency Analysis

Tutorial 2 offers an presentation of the configuration and setup procedure for measuring the electrical efficiency of an AC motor drive. This application features a single phase to three phase variable speed drive, the single phase AC input power is measured with the PPA1500 and the three phase output power is measured with the PPA5500. This tutorial also discussed the synchronisation of two power analyzers to our PPALoG software package. If the highest of accuracy is required, two PPA5500′s can be connected in a “master/slave” configuration, offering 0.1% nominal accuracy.
