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


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.
