Abstract
System and methods for providing power to a generator control circuit are provided. Aspects include a generator, a first power converter comprising a first input and a first output, the first input coupled to an output of the generator and the first output coupled to a valve circuit, a second power converter comprising a second input and a second output, the second input coupled to the output of the generator and the second output coupled to the valve circuit, and a controller configured to monitor a characteristic associated with the generator, cause the first power converter to provide power to the valve circuit when the characteristic of the generator is within a first range of characteristic values, and cause the second power converter to provide power to the valve circuit when the characteristic of the generator is within a second range of characteristic values.
