Abstract:
A trim head drive is provided. The trim head drive includes a nonlinear power supply. The nonlinear power supply includes an output and a return connected to a trim coil of a generator. An output of the nonlinear power supply directly drives a trim coil to control an output frequency of the generator. The nonlinear power supply varies the output positively and negatively to either sink or source a trim head current to control an output frequency of the generator.
