A method for providing electrical power at locations where shore power is unavailable, such as construction sites, remote utility sites, etc. Particularly, the method comprises simultaneously providing significant three phase power and significant single phase power. For example, in various instances the method comprises providing three phase power via generator of an integrated electrical power generation system, wherein the provided three phase power can be at least 50% of the rated power output of the generator, and simultaneously providing single phase power via a no-idle subsystem of the integrated power generation system, wherein the provided single phase power can be at least 3% of the rated power output of the generator.

A method for performing rotational speed synchronisation of a first transmission component having a first initial rotational speed with a second transmission component having a second initial rotational speed, so that they rotate with the same final rotational speed during a gear switch from an initial driving gear to a final driving gear in a stepped gear transmission for a hybrid electric or electric drive train having an electric traction motor. The method including calculating a total frictional work resulting from performing the total rotational speed synchronisation by means of a mechanical synchroniser of the stepped gear transmission only, and if the calculated total frictional work exceeds a maximal frictional work of the mechanical synchroniser, performing the rotational speed synchronisation by means of both the electric traction motor and the mechanical synchroniser.

A counter gear mechanism includes: a fifth gear in mesh with a third gear; a sixth gear in mesh with a fourth gear; and a seventh gear in mesh with a differential input gear. The seventh gear is disposed between the fifth gear and the sixth gear in an axial direction. A switching mechanism is disposed between the third gear and the fourth gear in the axial direction. The switching mechanism makes switching among: a state in which the third gear is coupled to a second input member; a state in which the fourth gear is coupled to the second input member; and a state in which the third gear and the fourth gear are decoupled from the second input member. This structure is able to make an entirety of an apparatus compact in size in the axial direction when the apparatus includes the switching mechanism to change the speed ratio between the second input member, which is drivingly coupled to an internal combustion engine, and output members.
