    摘要： The present invention relates to a power conversion system, comprising: a high voltage "HV" switchgear (3); a solid-state transformer (4); and a low voltage "LV" switchgear (5). The HV switchgear (3) is configured to connect to a high voltage or medium voltage "HV or MV" network (2) and disconnect from the HV or MV network (2). The HV switchgear (3) is configured to connect to an input of the solid-state transformer (4). The solid-state transformer (4) comprises a first module (11) and a second module (12). The first module (11) is configured to convert a high voltage alternating current "HV AC" signal into a high voltage direct current "HV DC" signal. The second module (12) is configured to connect to an output of the first module (11) and convert the HV DC signal from the first module (11) into at least one low voltage direct current "LV DC" signal. The second module (12) comprises at least one sub-module (13). Each sub-module (13) is configured to convert the HV DC signal from the first module (11) into a LV DC signal. The LV switchgear (5) is configured to connect to an output of the solid-state transformer (4). The LV switchgear (5) is configured to connect to a plurality of applications or devices (6) and disconnect from the plurality of applications or devices (6). The LV switchgear (5) comprises a plurality of switches, and each switch is connected to an application or device (6). The LV switchgear (5) is configured to connect the at least one LV DC signal from the second module (12) to one or more of the plurality of applications or devices (6).
