Abstract
A three-level boost converter and a control method. The three level flying-capacitor boost converter includes: an inductor, a flying capacitor, a controller, a first switching transistor and a second switching transistor as primary power transistors. When a voltage of the flying capacitor is less than or equal to a half of a bus voltage, a first driving signal is sent to the first switching transistor, and a second driving signal is sent to the second switching transistor; or when a voltage of the flying capacitor is greater than a half of a bus voltage, a first driving signal is sent to the second switching transistor, and a second driving signal is sent to the first switching transistor. The bus voltage is an output voltage Vo of the three-level boost converter.
