摘要：

A new switched-capacitor (SC)-based dc/dc boost converter is presented. It features good regulation capability and continuous input current, giving lower conducted electromagnetic interference with the supply network than classical SC converters. The converter is realized by using two quasi-switched-capacitor boost converter cells. The de voltage conversion ratio is controlled by the gate-source voltage of a quasi-switch in each cell, in order to adjust the charging trajectory of the capacitors. By renouncing inductive elements, the converter can be implemented in small size, lightweight, high power density and is possible to fabricate it in an IC form. ii prototype of a 20 W, 6 V/9 V dc/dc boost converter with overall efficiency of 74% and power density of 10 W/in(3) has been built. The state-space averaging technique is applied to study the static and dynamic behaviors of the converter.
