“…The following investigated configuration is promising for EVs-inverter-fed OEW BLDCM, shown in Figure 1, which combines one BM and one SCM, which through their inverters VSI 1 and VSI 2 are connected to the open ends of the motor armature winding [38]. With the help of different switching options of the inverter switches in different EV operating modes, the motor armature winding can be connected either to the BM or to the SCM at low EV speeds, or to two modules at the same time with the summation of their voltages at high EV speeds.…”

A modular approach to the construction of electric machines, drive systems, power supply systems is a new direction of modern technology development. Especially, the modular approach is promising for electric vehicles due to such positive aspects as increased efficiency, fault tolerance, overall reliability, safety, enhanced control capabilities, etc. In this work, the modular approach is comprehensively applied to an EV powertrain system, which includes a dual three-phase (DTP) BLDC motor with two machine modules of an asymmetric configuration, two battery modules and a supercapacitor module (SCM). The proposed H–H configuration of modular EV powertrain system includes four voltage source inverters that combine the power modules with the open ends of the windings (OEW) of the module machine armature, and provide control of their operation. Based on the developed mode system of the OEW machine module operation for EV traction and braking, a general control algorithm for the proposed configuration of the modular EV powertrain system has been developed. It combines the control of the operating modes with the functions of maintaining the required SOC level of the SCM and equalizing the SOCs of the two battery modules. The conducted simulation and experimental studies confirmed the workability and effectiveness of the proposed solutions.

“…Open-end winding BLDC motor drive is another drive topology being considered for high power applications. The open-end winding configuration not only enhances overall drive reliability but also enables the generation of multilevel voltage waveform across the motor windings [20]- [24]. In addition, for a given motor voltage, the DC link voltage required is half in the case of dual inverter-fed open-end winding BLDC motor drive compared to the traditional star-connected BLDC motor drive and hence the on-board supply voltage can be kept at a safe level in many applications.…”

This article presents a new multi-level voltage space vector structure-based control scheme for dual inverter-fed open-end winding BLDC (OEW-BLDC) motor drives, incorporating peak current control. An analysis of the voltage space vector structure of the OEW-BLDC motor drive is carried out first to identify the voltage vectors for developing two distinct PWM schemes tailored for low-speed and highspeed operations of the drive. The proposed scheme reduces the torque ripple in the drive due to the substantial reduction in the magnitude of the error voltage vectors while implementing the PWM scheme. In addition, this scheme ensures that only one inverter is switched at a time and the other inverter is clamped at a particular level, thereby reducing the switching losses. The multilevel voltage space vector structure-based switching also ensures that dv/dt is reduced substantially. The proposed scheme is verified by simulation as well as experiment on a laboratory prototype, employing a TMS320F28377S digital signal controller to implement the control algorithm.INDEX TERMS BLDC motor, peak current control, voltage space vector.
