In this article, a multilevel inverter (MLI) scheme is proposed for four-pole (4-pole), nine-phase (9-phase) induction motor (IM) drives with improved dc bus utilization as well as reduced device count. The proposed MLI is realized with nine three-switch inverter legs (3-SIL) and a single dc source.

IM-OFDMA: A Novel Spectral Efficient Uplink Multiple Access Based on Index Modulation
IEEE Transactions on Vehicular Technology, 2019This paper proposes a novel uplink multiple access scheme to enhance the overall spectral efficiency of wireless systems. The core idea is to exploit index modulation (IM) concept in orthogonal frequency division multiple access (OFDMA) systems. In the proposed scheme, entitled IM-OFDMA, part of the transmitted bits of each user is conventionally ...

Comparison of different PWM-VSI fed 3 Φ IM based on modulation index and switching frequency
2015 International Conference on Electrical, Electronics, Signals, Communication and Optimization (EESCO), 2015The research in Pulse width modulation schemes has been intensive in the last couple of decades. PWM techniques have been used to achieve variable voltage and variable frequency in ac-dc and dc-ac converters. The inverter gives out better sinusoidal voltage and current, so the speed controls of machines are considered beneficial.

Time-Frequency modulation is a two-dimensional modulation based on FSK and TSK, since it has strong anti-channel fading capability and its performance is far superior to FSK modulation due to its frequency diversity, time diversity and orthogonal coding error detection and error correction capabilities under the same channel conditions.
