Abstract: A buck-boost power converting system includes a voltage source input for connecting a voltage source for power conversion. A plurality of switches are connected electrically to the voltage source input, wherein each switch is connected to a controller configured for control of the switches. A voltage output is configured to connect to a load to power the load with converted power from the voltage source input, wherein the controller is configured to provide positive voltage or negative voltage at a desired level to the voltage output, as needed.

Abstract: A single input dual output buck-boost power conversion system includes a voltage source input for connecting a voltage source for power conversion. A plurality of switches electrically connect to the voltage source input, wherein each switch is connected to a controller configured for pulse width modulation (PWM) control of the switches. A first voltage output is configured to connect to a first load to power the first load with converted power from the voltage source input. A second voltage output is configured to connect to a second load to power the second load with converted power from the voltage source input, wherein the controller is configured to provide positive voltage or negative voltage to each of the first and second voltage outputs, as needed for any of four combinations of polarity among the first and second voltage outputs including positive-positive, positive-negative, negative-positive, and negative-negative.

Abstract: According to an aspect, a power supply is provided. The power supply includes a plurality of voltage converters including a first voltage converter and one or more other voltage converters. The power supply also includes a power supply control configured to perform a plurality of operations including enabling the first voltage converter during a start-up mode of operation, monitoring and regulating an output of the first voltage converter, reconfiguring the power supply control to enable the one or more other voltage converters based on determining that the output of the first voltage converter meets a regulation threshold, and transitioning from the start-up mode of operation to a regular mode of operation based on enabling the one or more other voltage converters to output one or more regulated voltages by the power supply.
