Abstract
A multi-level boost power converter circuit includes: at least two high-side switches; at least two low-side switches; a first capacitor; an inductor; and a control circuit configured to generate plural operation signals. The first end of the first capacitor is coupled between the at least two high-side switches, and the second end of the first capacitor is coupled between the at least two low-side switches. One end of the inductor is coupled to the input voltage, and the other end of the inductor is coupled to an inductor switching node, which is connected to either the first or second end of the first capacitor. The plural operation signals are configured to control the at least two high-side switches and the at least two low-side switches, thereby switching the voltage at the inductor switching node between a first divided voltage of the output voltage and the output voltage, or between the first divided voltage of the output voltage and a reference level.
