<p>An alternator has a three-phase output on lines 2, 3 and 4 applied to a DC - DC boost converter circuit 5 comprising rectifier means 7 and a chopper amplifier which includes transistors 11 and 12. The necessary inductance in the convertor circuit 5 is provided by the self-inductance of the alternator 1, thus allowing the normally separately provided inductances to be omitted, with consequent savings in cost, weight and space. Power components 7, 11, 12, 13, 14 of the convertor circuit 5 may be mounted on a heat sink and included in a common unit with the alternator 1. The heat sink and the alternator may share a common cooling circuit (21, Fig. 4). The system may be used to charge a battery in a hybrid electric vehicle. <IMAGE></p> |
