Abstract (en)

[origin: WO8800653A1] Engine start capability may be added to an aircraft generating system including a variable speed, constant frequency inverter (34) by placing transistors (48) in shunt relation to diodes (22) forming part of a full wave rectifier for rectifying A.C. power from a brushless generator output winding (10) which is normally supplied to the inverter (34) for conversion to constant frequency A.C. power. A source of D.C. power (60) may be connected to the diodes (22) and transistors (48) and the latter are operated by an inverter controller (52) to convert the D.C. power so provided to alternating current to be fed to the brushless generator output windings (10) and cause the brushless generator to operate as an A.C. motor for the starting of a turbine engine (18) or the like.
