Fig. 7.1-11 Dual system: (a) comparison of switching and split series/parallel hybrid drives, full line is mechanical connection and dotted
line electrical; (b) hybrid system; (c) transaxle configuration; (d) control strategy).

In the Emafer concept, Fig. 7.1-12, a flywheel motor/ permanent-magnet type while the converter uses high
generator unit is controlled by a power electronic con- frequency power switches. The flywheel is comprised of
verter. The flywheel (a) is of advanced composites con- four discs of tangentially wound prestressed fibre com-
struction and the motor/ generator of the synchronous posite, designed to achieve a modularity of energy capacity
