Control Strategy of a Five-Phase Induction Machine Supplied by the Current Source Inverter With the Third Harmonic Injection

In the five-phase induction machine (IM), it is possible to better use electromagnetic circuit than in three-phase IM. This requires of an adequate converter system which will be supplied by machine. The electric drive described, this article, includes current source inverter (CSI). proposed novelty—not presented previously—is control structures for IM, CSI. systems allow independent IM state variables first and second plane inject third harmonic. However, harmonic must suitably associated with fundamental solution, vector model not transformed into ( d–q ) coordinate that connected rotor flux but utilizes stationary xmlns:xlink="http://www.w3.org/1999/xlink">?–? ). nonlinear linearization based on demonstrated transformation i-orthogonal (i) planes.
