Abstract

A voltage converter is connected with a load. The voltage converter includes a power source, a first switching element, a second switching element, an energy storage inductor, an energy storage capacitor and N capacitor modules. The first switching element is connected between a first terminal of the power source and a first node. The second switching element is connected between the first node and a second node. A second terminal of the power source is connected with the second node. The energy storage inductor is connected between the first node and the third node. The N capacitor modules are connected between the third node and a fourth node, wherein N is a positive integer. The energy storage capacitor is connected between the fourth node and the second node.
