Lab 4 - Performance Indices

The objective of any performance index is to evaluate quantitatively and qualitatively the operation of an equipment and allow comparisons to be made between various configurations. The most used indices for AC/DC rectifiers and DC/AC inverters are presented in Table 1.

Performance Index	Expression

Performance Index	Expression
line-line rms output voltage [V_rms]
fundamental rms output voltage [V_rms]
rms line-line voltage harmonic spectrum
amplitude modulation ratio
frequency modulation index
phase current harmonics
avg. DC bus current [A]
line current [A]
