“…The DC port voltages of the FBCs in a symmetrical CC are always the same. The symmetrical CC has 2n + 1 voltage levels at the AC port, where n is the number of FBCs [19,20]. The benefits of symmetrical CC include easily modulated and even distribution of the power losses.…”

“…In addition, the issues of voltage balance in both diode-clamped MLCs and flying-capacitor MLCs have to be concerned [15][16][17][18]. The cascaded bridge MLCs connect several full-bridge converters (FBCs) to generate more output voltage levels and reduce the switching voltages of power electronic switches [19][20][21][22][23]. An independent DC source is necessary for each FBC, which is the primary consideration for cascaded bridge MLCs.…”

This paper develops a cascaded AC-DC power conversion interface (CADPCI) to convert AC power to charge the battery set. The proposed CADPCI is composed of a cascaded converter (CC) and a dual-input buck converter (DIBC). The CC is formed by connecting a full-bridge converter (FBC) and a bridgeless rectifier (BLR) in series. The CADPCI generates an 11-level input voltage and performs unity power factor correction. The switching loss is reduced because only the FBC with a lower DC port voltage is switched at a high frequency. The DIBC uses a buck converter and a selection switch set to generate a two-level DC voltage on the DC port of the BLR. By controlling the DC input voltage of the buck converter, the injected power of the BLR can match the input power of the utility. Therefore, the FBC does not require to handle the real power, saving an isolated converter for regulating the DC port voltage of the FBC, thus simplifying the power circuit of the CC. The buck converter also acts as a DC active filter to filter out low-frequency ripples of the charging current. A prototype is constructed to verify the performance of the proposed CADPCI.
