The main field of interest, in which the most scientific
papers were published, is the Electric
Vehicle (EV) application. Practically, all research projects in which I
was involved concerned the automotive field, and just a few of the papers are
dealing with renewables. Since the
major consumer on board of an EV is the propulsion system, several
perspectives and research topics have been tackled.

Figure above presents the
main studied topics on
the EV application - from 1 to 6 are given topics
which have achieved significant
results so far, and with FW1-FW4 ("Future-Work") are indicated further
concerns. The high
speed propulsion, the magnetic
transmission and the noise and
vibration issues, the RCP
(Rapid Control Prototyping) and HiL (Hardware in the Loop) simulation tools are perspective topics; some of them are in
early research stage and other just started. Among the
significant obtained results we emphasize here the
following:
·
Development for scalar and vector control strategies for
electrical machines and drives. ·
Development of algorithms for energy management for
batteries (Li-I) and ultracapacitors. ·
Prototypes construction: electrical machines for light EVs
(3 prototypes for special electric scooter), Fig.1; one in-wheel motor (with
outer rotor) for classic electric scooter, Fig.2-top; high speed permanent
magnet synchronous machine, water cooled, Fig.3; integrated motor-magnetic
gear (Fig.2-bottom) and high speed magnetic gear with fixed transmission
ratio, Fig.4; static converters of 500W-26kW with switching frequencies of
5kHz-64kHz (9 phases inverter with fault tolerance capability, Fig.5, buck
and boost dc/dc converters, Fig.6, etc.). ·
Development boards based on: DSP-TMS320LF2407
(Fig.7-left); dsPIC microcontrollers (Fig.7-right);
FPGA based resolver-encoder converter for position detection (Fig.8); high
precision and high frequency analog to digital conversion (ADC) units
(Fig.9). ·
Test bench development for: EV’s propulsion system
(Fig.10); vibro-acoustic behavior of electrical systems (Fig.11); source
characterization (Fig.12). ·
Software applications for process control and interfaces (HiL & RCP simulators have been build),
Fig.13. ·
Virtual Reality simulator for EV propulsion system testing
(Fig.14). ·
Mobile charging station (Fig.15). |
