Three Phase Inverter

In this paper, a new technique for diagnosing multiple open switch fault in three phase voltage inverter feeding induction motor is presented. It is based on the so-called the Lissajous curve of an auxiliary winding voltage Park components. For this purpose, expressions of the inserted winding voltage and its Park components are presented. Simulation results curried out for non defected and defected inverter show the effectiveness of the proposed method.

In this paper, a new technique for diagnosing faults in three phase voltage inverter feeding induction motor is presented. It is based on the so-called the voltage spectrum of an auxiliary winding. For this purpose, expression of the inserted winding voltage is presented. After that, discrete Fourier transform analyzer is required for converting the voltage signal from the time domain to the frequency domain. Simulation results curried out for non defected and defected inverter show the effectiveness of the proposed method.
