“…The fault occurrence can be determined by analysing the voltage error obtained from difference between the measured and estimated pole voltages. This voltage error is given by [3,4] .20 ms voltage space vector decomposition technique [5] .20 ms average currents Park's vector monitoring [6] .20 ms pole voltage measurement [7,8] .5 ms lower switches' voltage measurement [9] depending on the values of the analogue parameters (not experimentally reported) First we suppose that the switches are ideal. With this supposition in normal operation, the measured and estimated pole voltages are equal and thus their difference is zero.…”

“…In [3,4] analysis of the current-vector trajectory is used to identify fault modes. In [5], Klima studied time and frequency domain analysis of fault-tolerant space vector PWM VSI-fed induction motor drive. Mendes and Cardoso [6] have suggested using the average motor currents Park's vector monitoring, for diagnosing VSI faults in AC drives.…”

“…Finally, an original closed-form solution of line currents, based on the mixed p-z approach [2], [3] is introduced. To verify the validity and effectiveness of the proposed control strategy, the analytical and experimental results based on laboratory setup are provided.…”

“…The unsymmetrical sequence can be expressed by means of the discrete Fourier transform in the symmetrical form as follows from [3] Thus, the unsymmetrical sequence can be decomposed into two symmetrical ones (6). The first sequence has a positive direction of rotation with the amplitude Vd (1 + 3)/6 and the second sequence has a negative direction of rotation with amplitude Vd, (1 -3)/6.…”

“…In terms of the signature to identify fault elements in an inverter, the phase voltages [2], d-q phase currents [3] and mean phase currents [4] are often used. Some researches introduced detection and diagnosis methods such as modelbased techniques [5], intelligent systems [6] and so on.…”
