초록

A control circuit for a generator has a control function that monitors the voltage across a bus capacitor. The circuit delivers excess voltage back to associated stator windings if an unduly high voltage is detected across the bus capacitor.

What is claimed is: 1. A starter/generating system comprising: a plurality of stator windings connected to a start inverter, a bus capacitor mounted in parallel with a load, and a power source for being selectively connected to said stator windings through a start/generate switch, said start/generate switch moving to a generate position to connect said stator windings to said load; a control for controlling said start inverter to allow the flow of power from said power source to said stator windings in one position, and to allow the flow of power from s...
