This paper proposes a cascaded modular high-power motor drive converter with a quad-port isolated DC/DC converter (QAB) as the core circuit. Compared with conventional topologies of high-power motor drive converter, the proposed converter can significantly reduce the double-fundamental-frequency power fluctuation on the dc side of the cascaded H-bridge, thus significantly reducing the required capacitance. More than 100 times capacitance reduction has been achieved under the same condition. The inter-phase power balance can be also achieved easily by applying identical controls on three outputs of QAB converter. Finally, theoretical analysis and simulation results have verified the operation and performance of the proposed topology.
