Induction motors are normally used in the industrial environments. Industry has begun to use energy efficient high power rating electrical drives. Multilevel inverter drives have become a solution for energy efficient drives in recent years. There may be probability for occurring of many faults in the multi-level inverter fed induction motor drive due to its complex switching patterns. So it is necessary to identify types of fault and its location in order to improve the reliability of the drives. In this paper presents a new fault diagnosis technique based on discrete wavelet transforms for H-bridge multilevel inverter drives. For demonstrating the proposed method one H-Bridge open circuit fault are considered in the H-Bridge multilevel inverter. The 30V prototype system is developed and controlled by Renesas processor. LabVIEW based data acquisition system is used to acquire the real time inverter output voltage and current. The experimental results are shown to illustrate the effectiveness of the proposed method.
