The main goal of the project is the research and development of a reliable electric power train to promote the massive use of electric
vehicles in a clean urban environment.
Electric Vehicle (EV) Technologies continue high on academic and industrial research agendas and innovative technologies of low cost
high efficiency electric motors, as ferrite-assisted SynRM supplied by high temperature energy efficient SiC power converters are solutions
currently investigated.
However, successful mass production and overall acceptance of EV depends on reliability, apart from fuel economy, energy efficiency and
In this context, reliability can be defined as the capability of the EV to perform properly under predefined conditions for an established
period of time, even operating under certain degree of faulty conditions. To this extent, advance control and fault tolerance for the most
robust and reliable powertrains must be considered in future electric powertrains.
Accordingly, robustness, reliability and fault tolerance are the new exciting challenges to face for the next generation of electric
powertrains, especially those based on the new rare-earth free motors and high-voltage wide-bandgap (WBC) devices. To this extent,
multiphase motor drives have gained a growing interest because they allow the design of very compact high efficiency drives with intrinsic
fault-tolerant capabilities, apart from other intrinsic advantages such as reducing the amplitude and increasing the frequency of torque
pulsation, reducing the stator current per phase without increasing the voltage per phase and lowering the dc link current harmonics.
Therefore, the general objective of the project is to investigate, design, develop and verify a new high power density, efficient and reliable
electric power train, based on multiphase PMa-SynRM motor driven by SiC converters. Enhanced power converters and motor control
characteristics regarding fault tolerance and reliability will be achieved by optimal power converter design and intelligent active gate driving
(efficiency and EMIs), fault detection and fault mitigation by redundancies and management of the faulty operation modes and control
access to neutral point of the motor, which in case of fault will allow fault tolerant control and balance of the thermal stress along the stator
core to output power of the machine regarding efficiency
Specific objectives are as follows:
1. Research and development of a mechanically, electrically and thermally optimized Fault Tolerant five phases SiC Power Converter.
2. To increment multiphase power converter reliability by research and development on fault detection and mitigation and intelligent active
gate driving
3. To research on the multiphase PMa-SynRM fault patterns and motor fault modes, and development of fault detection and diagnosis
4. To research and develop of a Fault Tolerant Control of the Electric Power Train with multiphase PMa-SynRM motor driven by a SiC
5. To research and develop a system - level reliability prediction model of the EV powertrain with multiphase PMa-SynRM motor driven by
a SiC Converter
6. Experimental validation of Reliable and Fault Tolerant multi-phase Powertrain based on a PMa-SynRM driven by a SiC Converter.
7. Diffusion of the Research Results and transference of knowledge and technology to industrial world.
