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.

This work considers the existing approaches and devices for the composition analysis of multiphase medium are considered. A new technique for analyzing three-phase mediums based on the wave dispersive analysis of radiation is proposed. The fluxes of a multiphase fluid, composite materials, etc. can act as the mediums. Preliminary estimates show that the sensitivity is about 0.25% of the oil content in water and 1% of the content of gas.
