Advanced

Belt Driven Alternator and Starter with a Series Magnetized Synchronous Machine Drive

Bergh, Tomas LU (2006)
Abstract
Electric Hybrid Vehicles, EHV, are under development to provide lower fuel

consumption levels and minimize the environmental pollution compared to

pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more

complex and thus carry many more extra parts than the pure ICE based

vehicle. Competing against the pure ICE vehicle in the sense of nonexpensive

mass production is hard.

This thesis is a result of a research project with the goal to develop a complete

Belt driven Alternator and Starter, BAS, system for a Stop&Go functionality

as a cost-effective hybrid vehicle solution. BAS is based on a Series

Electric Hybrid Vehicles, EHV, are under development to provide lower fuel

consumption levels and minimize the environmental pollution compared to

pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more

complex and thus carry many more extra parts than the pure ICE based

vehicle. Competing against the pure ICE vehicle in the sense of nonexpensive

mass production is hard.

This thesis is a result of a research project with the goal to develop a complete

Belt driven Alternator and Starter, BAS, system for a Stop&Go functionality

as a cost-effective hybrid vehicle solution. BAS is based on a Series

Magnetized Synchronous Machine, SMSM, which as an adjustable-speed

drive system comprises power electronics but excludes permanent magnets.

BAS is a rather old concept. It merges two functions, an electric starting

motor and an generator, into one single electric machine. It thereby makes

the total system lighter and smaller. Furthermore, it facilitates technology

leaps on the road towards mass production of electric hybrid vehicles.

The developed BAS system is suitable for a midrange passenger vehicle. The

Stop&Go functionality provides an ICE turn-off at each vehicle stop. The

SMSM is, in addition to generating electricity and starting the ICE, intended

to support the ICE with an additional torque when it is assumed beneficial in

the sense of reaching low fuel consumption.

Topics in the field of power electronics and control of the SMSM that are

covered in this thesis are:

• Simulations on vehicle basis are performed for optimizing the rated

power of the electric machine and its power electronics in the sense

of low fuel consumption.

• The Series Magnetized Synchronous Machine, SMSM, and the

theory lying behind it are presented. The SMSM is carefully

investigated both magnetically and electrically.

• A simulation model for the SMSM is derived based on the

theoretical model that describes the SMSM.

• Based on the theoretical model of the SMSM, dedicated current

controllers are derived. Other types, as standard PI controllers and a

so-called field voltage vector feed forward controller are investigated

and simulated for control of the SMSM.

• The SMSM is tested in laboratory environment for confirming the

behaviour of the derived model of the adjustable-speed drive system

including its power electronics. (Less)
