摘要： An alternator system having an alternating current voltage source includes a rectifier coupled to the voltage source, a sensor coupled to the voltage source and an engine and a control circuit coupled to the voltage source, the rectifier and the sensor. The control circuit provides control signals to the rectifier and the voltage source. The alternator system further includes a fault protection controller coupled to an output of the alternator system and coupled to the control circuit. The rectifier operates such that the alternator system provides a load match which results in output power levels which are relatively high compared with output power levels of conventional alternator systems and the fault protection controller operates under fault conditions (e.g. load dump), and overrides the other controllers in the alternator system based on output voltage when a load dump occurs.

摘要： Markov chain controlled random modulation of switching signal sequences of for a power converter. The control is implemented in a power converter having an energy storage device which receives an input power from a source and provides an output power to a load. The converter includes a switching device for coupling the input power source to the energy storage device or coupling the storage device to the load in response to receiving a sequence of control signals generated from a control signal generator. The control signal generator includes a switching signal generator for providing a nominal switching signal sequence which achieves steady state between the input power to the converter and the output power supplied to the load, a modulator for modulating the nominal switching signal sequence with a source of non-deterministic signals to produce a time modulated switching signal sequence, and a control device for controlling the modulator in response to determining the previous modifications performed to the nominal switching signal sequence to maintain a predetermined range of deviation between the time modulated switching signal sequence and the nominal switching signal sequence.
