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.
