Abstract
A buck-boost converter is described that includes input terminals, output terminals, a first group of devices, a second group of devices, an inductor, a capacitor, and a controller. Each group of devices includes a first switch, a second switch, and a third switch or diode connected in series. Each group of devices further includes a first node located between the first switch and the second switch, and a second node located between the second switch and the third switch or diode. A first of the input terminals is connected to the first node of the first group of devices, and a second of the input terminals is connected to the first node of the second group of devices. The inductor is connected between the second node of the first group of devices and the second node of the second group of devices. The first group of devices, the second group of devices, and the capacitor are connected in parallel across the output terminals, and the controller controls the switches of the first group of devices and the second group of devices.
