Abstract
A vehicle, e.g., an off-road vehicle, may include an internal combustion engine, a starter motor coupled to the engine via a multi-stage transmission during a starting process, a further electric machine coupled to a crankshaft of the engine, and a converter arranged to supply at least one energy storage unit, e.g., a battery. The converter may be configured as a 4-quadrant regulator having a B6 circuit of MOSFETs.
Claims13
A vehicle, including:
- a combustion engine with less than six cylinders,
- a starter motor configured to drive the combustion engine,
- a multi-stage transmission, wherein the starter motor is configured to drive the combustion engine during a starting process, and
- wherein, following the starting process, the starter motor is decoupled from the combustion engine via an uncoupling mechanism,
- an electric machine, distinct from the starter motor, configured to be operated as a motor and generator, having a fixed connection to a crankshaft of the combustion engine and by which the combustion engine is able to be driven, and
- a converter, having an electrical connection with windings of the electric machine, and which is configured to convert an alternating current generated by the electric machine to a direct current,
- wherein the converter is configured to supply at least one energy store in the form of a battery, and
- wherein the converter comprises a 4-quadrant regulator comprising a B6 bridge circuit of metal-oxide-semiconductor field-effect transistors (MOSFETs).
