Summary:This study explores the benefits of using the resonance principle in induction machines. It allows the machine to apply high current density with low DC link voltage. However, the resonant machine requires high voltage at low frequencies, which limits its ability to achieve high torque density during acceleration or deceleration. The study compares the performance of an asymmetrical six-phase conventional, resonant, and hybrid resonant induction machine. All three machine configurations are controlled using indirect rotor-field oriented control and a current-sharing technique. To validate both topologies experimentally, a high-speed induction machine is used. The results show that the hybrid resonant machine possesses a higher torque density at lower speeds than the resonant machine. However, the resonant machine demonstrates greater power density at higher speeds than the hybrid machine. Nonetheless, the hybrid machine surpasses the induction machine by producing three times the torque at high speeds.
