초록

In a system for starting an aircraft turbine from a low voltage direct current power supply, the low voltage power supply is coupled by an invertor to the turbine\s a.c. generator. The generator operates as a motor during starting. The invertor is initially coupled directly to the generator during starting, and to the generator via a step-up transformer after the speed of the generator increases. In a preferred embodiment of the invention, the transformer is an autotransformer used to step down the output of the generator when operating as a generator af...
