Feasibility of operation of a new procedure to start a jet engine (JE) and to generate power by means of a single induction machine (IM) directly coupled to the turbine has been shown by means of a hardware prototype. An introduction, background, operation principle of this type of a system and software simulation portion was presented in Part I of this article. Both in software simulation and in the experimental phase of the studies the JE is replaced by a de machine. The de machine is brought to an initial speed by the motoring operation of the IRI. Later, the IM is taken into generating mode and the de machine is into motoring mode of operation, This mode would correspond to the turbine catch-up initiation phase and initiate driving phase of the induction generator (IG) in the actual world, The generated power is then converted to a three-phase 3 empty set, 400 Hz tin software), 60 Hz tin hardware), 115 V voltage-regulated bus via a double stage power conversion utilizing a 20 kHz parallel resonant high frequency (HF) ac link and pulse density modulated (PDM) converter technology. Independent of the coupled machine speed, a constant amplitude and constant frequency 3 empty set voltage-regulated ac bus is formed and maintained by the proper control of the power converters.
