Abstract: This disclosure includes novel ways of implementing a power supply that powers a load. A main battery source produces a main battery voltage; each of multiple auxiliary battery sources in a set produces a respective auxiliary battery voltage. A controller initially sets a battery supply voltage to the main battery voltage, the main battery voltage is supplied to a power converter. The controller then monitors a magnitude of the battery supply voltage and adjusts the battery supply voltage supplied to the power converter based on a comparison of the magnitude of the battery supply voltage with respect to a threshold level. The adjusted battery supply voltage is provided from a serial connection of the main battery source and a first auxiliary battery source in the set.

A method of producing the voltage regulator module and electronic assembly that includes the voltage regulator module are also described.

Abstract: A first partial power converter implementation receives and converts an input voltage into multiple auxiliary voltages including a first auxiliary voltage and a second auxiliary voltage. The first partial power converter produces a first output voltage as a first summation of the first auxiliary voltage and the input voltage; the first partial power converter produces a second output voltage as a second summation of the second auxiliary voltage and the input voltage. A second partial power converter implementation as discussed herein receives a first auxiliary input voltage referenced with respect to an output voltage of the power converter. The second partial power converter also receives a second auxiliary input voltage referenced with respect to the output voltage. The second partial power converter converts the first auxiliary input voltage and the second auxiliary input voltage into the output voltage to power a load.

Abstract: This disclosure includes novel ways of implementing a power supply that powers a load. More specifically, a power supply includes a bidirectional power converter and a controller. The controller monitors a magnitude of an input voltage supplied from an input voltage source to a load. Based on a magnitude of the input voltage, the controller switches between a first mode of operating the bidirectional power converter to charge an energy storage resource using (a portion of power provided by) the input voltage and a second mode of producing a backup voltage from the energy storage resource to power the load as a substitute to the input voltage such as when the input voltage is below a threshold value.

Abstract: A power supply includes a first (main) power converter and a second (auxiliary) power converter disposed in parallel with the first power converter to produce an output voltage to power a dynamic load. The second power converter includes a primary inductive path magnetically coupled to a secondary inductive path. A controller controls a flow of first current through the primary inductive path of the second power converter to control flow of second current supplied by the secondary inductive path to the dynamic load. During steady state conditions, the first power converter produces the output voltage while the second power converter is deactivated. During transient load conditions, the second power converter provides current boost capability to maintain a magnitude of the output voltage within a desired range.
