摘要：Disclosed are a DC-DC converting method, a DC-DC converting apparatus and a DC-DC converting circuit. A double step-down DC-DC converting method may comprise the steps of: a double step-down DC-DC converter receiving a first voltage; and the double step-down DC-DC converter converting the first voltage into a second voltage on the basis of a plurality of operational modes, wherein the double step-down DC-DC converter comprises a primary circuit and a secondary circuit for converting voltage, the primary circuit comprises a first full-bridge circuit connected in series to a first switch, and the first full-bridge circuit comprises a first leg and a second leg connected in parallel and an input pressure wire connecting the first leg and second leg, a double step-down capacitor and a third switch are implemented on the first leg, and a second switch and a fourth switch can be implemented on the second leg.
