Abstract: A power conversion system includes a high voltage (HV) switchgear; a solid-state transformer; and a low voltage (LV) switchgear. The HV switchgear connects to and disconnects from a HV network. The HV switchgear connects to an input of the solid-state transformer, which comprises first and second modules. The first module converts an HV alternating current (AC) signal into a HV DC signal, and the first module converts an HV DC signal into an HV AC signal. The second module converts an HV DC signal into at least one LV DC signal, and the second module converts at least one LV DC signal into an HV DC signal. The LV switchgear connects to an output of the solid-state transformer. The LV switchgear connects to a plurality of applications or devices and disconnects from the plurality of applications or devices.

Abstract: A power conversion system includes a high voltage (HV) switchgear; a solid-state transformer; and a low voltage (LV) switchgear. The HV switchgear connects to and disconnects from a HV or medium voltage (MV) network. The HV switchgear connects to an input of the solid-state transformer. The solid-state transformer comprises a first module and a second module. The first module converts a HV alternating current (AC) signal into a HV direct current (DC) signal. The second module connects to an output of the first module and converts the HV DC signal from the first module into at least one LV DC signal. The second module comprises at least one sub-module that converts the HV DC signal from the first module into a LV DC signal. The LV switchgear connects to an output of the solid-state transformer.
