PWM Inverter Power Measurement System Required for Evaluating the Efficiency of Advanced Motor Drive Systems


#1

Measuring power accurately in the inverter switching frequency and its harmonic frequency domain is critical in order to properly evaluate the performance of high efficiency motor drive systems. A power measurement system combining the Hioki Power Analyzer PW6001 that delivers superior performance and a phase shift function with newly developed Hioki AC/DC Current Sensors CT6875 / CT6876 / CT6877 can lead to accurate efficiency evaluation of such systems.
