Abstract-this paper proposes a hybrid modulation method for a dual-output five-leg indirect matrix converter topology. The proposed control technique combines a space vector modulation scheme (SVPWM) applied to the rectifier stage so as to control the input currents and a new digital scalar modulation scheme (DSPWM) designed to control the two loads output voltages. A generalized expression of the output voltage references is also developed showing the capability of the proposed method to control more than two independent loads without requiring additional mathematical development. Furthermore, a new modified expression of the output voltages references is proposed to enable the correct operation of the converter under unbalanced grid voltages. Also, the paper proposes a detailed mathematical analysis that allows evaluating the effect of output loads unbalances on the input current harmonic content. Simulation and experimental results are provided to show the effectiveness of the proposed theoretical investigations and confirm the capability of the proposed method to control multiple drive systems as well as ac input currents.Index Terms-ac/ac conversion, carrier-based pulse width modulation (SPWM), dual-output converter, faulttolerant operation, grid-connected converters, load unbalance, matrix converters, multi-drive systems, scalar modulation, space vector modulation (SVPWM), unbalanced grid voltages.

“…Among the several PWM approaches for this topology, it seems that the suggested method in [17,23] that uses all 32 possible voltage vectors of a five-leg converter, produces less voltage harmonics and is simpler and better suited for practical implementation. In this method a so called "double zerosequence injection method" is used.…”

“…In [26], a micro control unit with control law accelerator architecture is proposed, which integrates the dual-motor control and power factor correction functions in a single controller for heating ventilation and air conditioning drives. Independent current control schemes for a dual three-phase induction motor (IM) drive fed by a five-leg inverter is considered in [27], [28], by using an existing pulse width modulation (PWM) technique in conjunction with fieldoriented control.…”

Abstract-Switched reluctance motors (SRMs) have been considered as a potential candidate for automotive applications due to its rare-earth-free feature and wide speed range. Conventionally, a current sensor is installed in each phase for the current regulation control, which will considerably add the cost and volume to multi-motor drives. This paper proposes an independent current control technique for dual parallel SRM drives using only one current sensor. In order to identify the individual motor currents from the public current, a pulse injection scheme is developed accordingly. Two pulses are individually injected into the lower-transistors of the dual converter in the excitation regions; and the fixed current sampling points triggered by the injected pulse are presented for motor current identification. The independent current control for the dual SRM can be directly implemented by the public current sensing although the motor parameters are different. The developed system requires only one current sensor without additional hardware or reduced system performance. The simulation and experimental results on parallel 750 W and 150 W three-phase 12/8 SRM drives are presented to confirm the effectiveness of the proposed method. With this scheme, the dual motor drive can be more compact and cost-effective for traction drive applications.
