摘要
A modular power conversion device includes at least one first-type energy storage device (ESD) configured to induce a first direct current (DC) voltage, and at least one active power link module (APLM) string coupled to the at least one first-type ESD. The at least one APLM string includes a plurality of APLMs coupled to each other. Each APLM of the plurality of APLMs has a plurality of switching devices including a first switching device and a second switching device coupled to each other in electrical series. Each APLM of the plurality of APLMs also has at least one second-type ESD coupled in electrical parallel with both of the first switching device and the second switching device. The at least one second-type ESD is configured to induce a second DC voltage.
