RFOC implementation in four‐switch three phase inverter‐fed induction motor drive

Purpose – This paper seeks to discuss the implementation of the rotor flux oriented control (RFOC) in a four‐switch three‐phase inverter (FSTPI)‐fed induction motor drive.Design/methodology/approach – The implementation is achieved considering a current regulation of the FSTPI. Such a regulation is done thanks to bang‐bang regulators. As far as the FSTPI is fed by a battery pack, the paper considers an electrical equivalent circuit of such a power supply.Findings – Simulation works, carried out considering the case of an ideal model of the battery pack and the case where the electrical equivalent circuit of the battery pack is taken into account, have shown that the drive dynamic performance are practically the same. Furthermore, and in order to highlight the performance of the induction motor fed by a FSTPI, these are compared with those obtained with the induction motor fed by a conventional six‐switch three‐phase inverter (SSTPI), considering both models of the battery pack. It has been found that the ...
