Abstract
The present disclosure relates to a buck-boost converter and a control method therefor. The buck-boost converter includes a boost unit and a buck unit. The boost unit has a first capacitor and a first group of switches. The buck unit has an inductor and a second group of switches. The buck-boost converter has a cascaded structure of the boost unit and the buck unit to achieve multiple voltage conversion modes. The inductor of the buck unit is coupled to the output terminal. Therefore, not only can it achieve a smooth transition of the DC output voltage, but also reduce voltage ripple and improve dynamic response speed.
