Abstract

A power converter is provided. The power converter includes first to fourth switches electrically connected in series, a flying capacitor and a controller. Positive and negative terminals of the flying capacitor are electrically connected to the second and third switches respectively. The controller operates the first and fourth switches to perform a first complementary switching with a first dead time, and operates the second and third switches to perform a second complementary switching with a second dead time. The controller determines to regulate the first or second dead time by detecting a capacitor voltage of the flying capacitor, such that the capacitor voltage of the flying capacitor is maintained within a balance voltage range.
