Abstract
A power conversion circuit converting power between a bus voltage at a bus node and a first voltage at a first node includes: a bus switch coupled between the bus node and a second node which has a second voltage; plural conversion switches coupled, with at least one conversion capacitor, to the first node and the second node. In a power conversion mode, the plural conversion switches convert a power between the second voltage and the first voltage via a switched capacitor power conversion method, and plural sub-clamp circuits respectively clamping a drain-gate voltage of respective switch of a group of switches to not exceed a drain-gate clamp voltage, so that when the bus node is applied with a bus maximum rating voltage, respective drain-source voltages of the bus switch and the respective switch in the respective corresponding plural conversion switches are smaller than a corresponding breakdown voltage.
