Power module, multi-port power converter and energy system comprising the same

The present disclosure relates to a power module, a multi-port power converter and an energy system comprising the same. A power module according to the present disclosure comprises a first module port configured to be electrically connected to a power element, the power element being a storage, source and/or load; a second module port configured to be electrically connected to a transformer port of a multi-port transformer; a converting unit comprising a switching unit electrically connected between the first module port and the second module port, wherein the converting unit is configured to, using the switching unit, convert DC power received at the first module port to AC power at the second module port or convert AC power received at the second module port to DC power at the first module port; and a control unit configured to detect an AC voltage signal received from the multi-port transformer at the second module port, generate a control signal based on a frequency and phase of the detected AC voltage signal, and control the switching unit using said control signal.
