Abstract
A switched tank converter includes at least three conversion units. Each conversion unit is a first-type conversion unit or a second-type conversion unit. An end of the support capacitor of each first-type conversion unit is electrically connected with a ground end. An end of a half-bridge clamping circuit of the second-type conversion unit is electrically connected with the ground end. A middle point of the half-bridge clamping circuit is electrically connected with an end of the support capacitor of the second-type conversion unit. The first-stage conversion unit is the first-type conversion unit. At least one conversion unit of the third-stage conversion unit to the Nth-stage conversion unit is the second-type conversion unit. Another end of the half-bridge clamping circuit of at least one second-type conversion unit is electrically connected with another end of the support capacitor of the lower-stage conversion unit excluding the first-stage conversion unit.
