Since a multi level converter is no

Since a multi level converter is normally used in medium to high power applications,the
reliability of the multilevel converter system is very important. For instance industrial drive
applications in manufacturing plants are dependent upon induction motors and their inverter
systems for process control. Generally, the conventional protection systems are passive devices
such as fuses, overload relays, and circuit breakers to protect the inverter systems and the
induction motors. The protection devices will disconnect the power sources from the multi level
inverter system whenever a fault occurs, stopping the operated process. Down time of
manufacturing equipment can add up to be thousands or hundreds of thousands of dollars per
hour, therefore fault detection and diagnosis is vital to a company’s bottom line. In order to
maintain continuous operation for a multi level inverter system, knowledge of fault behaviors,
fault prediction, and fault diagnosis are necessary. Faults should be detected as soon as possible
after they occur, because if a motor drive runs continuously under abnormal conditions, the drive
or motor may quickly fail.

Karena converter multi level biasanya digunakan dalam media untuk aplikasi daya tinggi,
keandalan sistem konverter bertingkat sangat penting. Misalnya berkendara industri
aplikasi di pabrik tergantung pada motor induksi dan inverter mereka
sistem untuk pengendalian proses. Secara umum, sistem perlindungan konvensional adalah perangkat pasif
seperti sekering, relay overload, dan pemutus sirkuit untuk melindungi sistem inverter dan
motor induksi. Perangkat perlindungan akan memutuskan sumber listrik dari multi level
sistem inverter setiap kali kesalahan terjadi, menghentikan proses dioperasikan. Down time dari
peralatan manufaktur dapat menambahkan hingga menjadi ribuan atau ratusan ribu dolar per
jam, karena itu kesalahan deteksi dan diagnosis sangat penting untuk bottom line perusahaan. Dalam rangka
mempertahankan operasi terus-menerus untuk sistem multi level inverter, pengetahuan tentang perilaku kesalahan,
prediksi kesalahan, dan diagnosis kesalahan diperlukan. Kesalahan harus dideteksi sesegera mungkin
setelah terjadi, karena jika motor penggerak berjalan terus menerus dalam kondisi normal, drive
atau motor yang cepat mungkin gagal.
