ABSTRACT:
The same electrical machine geared to the fly-wheel of a vehicle engine serves as the starter and as the generator. This machine is excited by permanent magnets on a rotor and its stator is wound with two phase windings offset from each other by 90.degree. electrical. Half-bridge rectifiers are utilized in a circuit cooperating with the center tap of each winding for charging the battery in generator operation, cooperating with a unit including at least one MOSFET for regulating the charging current. In motor operation the winding center taps are connected to one pole of the battery and the common connection of the MOSFETs is connected to the other pole of the battery so that these devices can operate as d.c. to a.c. converter elements for providing pulses in proper sequence to the erstwhile generator to make it operate as a motor.
