Abstract: A power converter is configured to increase bandwidth in response to a magnitude of the difference between the target output voltage and the actual output voltage. The converter includes a subtractor to receive a reference voltage and a scaled output as inputs, configured to produce an error as output, a functional block configured to receive the error as input and to produce a functional block output, a first multiplier configured to receive the functional block output and scale the functional block output by a first loop constant, and a second multiplier configured to receive the functional block output and scale the functional block output by a second loop constant. The functional block is configured to increase the error value fed to the first multiplier and the second multiplier by a factor f(x).

Abstract: A power supply system includes multiple power converters, each having an input and an output. The outputs of the power converters are connected together in parallel to produce a single system output. There is a shared command bus that is coupled to each one of the power converters. A control loop in (associated with) a designated one of the power converters is operable to generate a current command signal to be output onto the shared command bus. All of the parallel connected power converters in the power supply system are configured to receive the current command signal from the shared command bus and to adjust an amount of electrical current being supplied by that power converter in response to the current command signal.
