    IPC: H02J7/00

    Abstract: A controller for generating a control parameter of a feedback system may include a proportional path comprising a first selector configured to select one of a plurality of proportional signals to generate a proportional path output, wherein each of the proportional signals is based on a respective one of a plurality of error signals, each of the plurality of error signals associated with a respective regulated physical quantity, an integral path comprising a second selector configured to select one of a plurality of integral signals as a second selector output, wherein each of the integral signals is based on a respective one of the plurality of error signals and a single integrator configured to accumulate successive samples of the second selector output to generate an integral path output, and combiner logic configured to combine the proportional path output and the integral path output to generate the control parameter.

    Abstract: A system may include a power source, a power converter having an input coupled to the power source and an output for supplying electrical energy to a load, and a control circuit for controlling operation of the power converter. The control circuit may include a first feedback control subsystem configured to monitor an output voltage present at the output of the power converter and regulate the output voltage at or about a predetermined regulated voltage level in a normal mode of operation of the power converter and a second feedback control subsystem configured to monitor an input voltage present between the power source and the input of the power converter and responsive to the input voltage decreasing below a predetermined minimum voltage level, causing the power converter to operate in a protection mode of operation in order to maintain the input voltage at or about the predetermined minimum voltage level.

    Abstract: A method of randomizing inductor current in at least one of a plurality of parallel coupled peak/valley current-controlled power converters may include comparing the inductor current to a threshold to generate a comparison signal, delaying the comparison signal by a plurality of delay amounts to generate a plurality of delayed versions of the comparison signal, and randomly selecting one of the plurality of delayed versions of the comparison signal for controlling the inductor current during one or both of a charging state and a transfer state of the at least one of the plurality of parallel coupled peak/valley current-controlled power converters.
