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.
