Abstract:
1. A transmission arrangement for transmitting power from a prime mover having a controllable variable output to an output shaft associated with an input shaft of an electrical generator, the transmission arrangement comprising: a continuously variable transmission (CVT) so configured as to receive power from the variable output of the prime mover and to provide a CVT power output; the CVT having a variable transmission ratio; an alternative transmission so configured as to receive power from the variable output of the prime mover and to provide an alternative transmission power output; and a power mixing mechanism so configured as to combine the CVT power output and the alternative transmission power output into a combined power output to be supplied to the output shaft; an electronic controller so configured as to adjust the transmission ratio of the CVT in response to a change in a load demand at the electrical generator; the adjustment of the transmission ratio of the CVT causes an adjustment in the percentage of CVT power within the combined power output; wherein a percentage of CVT power within the combined power output decreases as power supplied by the prime mover increases.
