Harmonic qhov chaw: rectifier, inverter
Cov khoom siv Harmonic: hloov hluav taws xob, cua txias, of elevator, LED
Sab nraud CT kuaj pom cov load tam sim no, DSP raws li CPU muaj kev tswj xyuas cov lej lej siab tshaj plaws, tuaj yeem taug qab cov lus qhia tam sim no, faib cov khoom thauj tam sim no rau hauv lub zog ua haujlwm thiab lub zog reactive los ntawm kev siv lub ntse FFT, thiab suav cov ntsiab lus sib haum xeeb sai thiab raug.Tom qab ntawd nws xa PWM teeb liab mus rau sab hauv IGBT lub rooj tsav tsheb los tswj IGBT rau thiab tawm ntawm 20KHZ zaus.Thaum kawg tsim cov nyiaj them rov qab rau theem tam sim no ntawm inverter induction, tib lub sijhawm CT kuj pom cov zis tam sim no thiab cov lus tsis zoo mus rau DSP.Tom qab ntawd DSP ua qhov kev tswj xyuas qhov tseeb tom ntej kom ua tiav qhov tseeb thiab ruaj khov dua.
