Abstract
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.
