| Abstract |
The paper describes a comparative study of low
voltage and high voltage SR machines for use in an
automotive turbo-generator exhaust gas energy recovery
system. Their relative merits, in terms of the total machine
loss and the loss distribution, are quantified. It is shown that
the requirement for an integer number of turns imposes
severe restrictions on the design of the low voltage system,
whereas the flexibility to employ various winding designs in
the high voltage system can be exploited to advantage. A
comprehensive analysis of both the winding design and the
operating control angles is presented. While the magnitude
of the total machine loss is relatively insensitive to the
operating voltage, the copper loss at full load is significantly
lower in the high voltage system. The merits of operating the
system at high voltage, in terms of the thermal rating of the
electric machine, are also discussed. |
