? aircraft departure and generation system, method of controlling an aircraft and aircraft departure and generation system?

摘要

It is an aircraft starter and generator system that includes a starter / generator that includes a main engine, an exciter, and a permanent magnet generator. The system also includes an inverter / converter / controller that is connected to the starter / generator and generates AC power to drive the starter / generator in a starter mode to start an aircraft main engine, and which converts ac power, obtained from the starter / generator after the main engine has started, to dc power in a dc generation mode. a load leveling unit (llu) is selectively coupled with a starter / generator dc power output and has an inverter / converter / controller (icc) with a field effect transistor based bridge configuration llu metal oxide semiconductor device that supplies dc power to dc power output in a supply mode, and receives dc power from the dc power output in a receive mode. an llu bridge gate trigger is configured to trigger the llu mosfet based bridge during a supply mode and a receive mode using bipolar pulse width modulation (pwm).
