1. A multiport energy routing system comprising:
device ports configured to be electrically coupled to devices and configured to control power flow between the multiport energy routing system and the devices;
a step-down transformer having:
a high voltage side configured to be electrically coupled to an AC utility grid; and
a low voltage side;
a power converter stack comprising:
power converter modules; and
one or more multiplexers;
wherein each power converter module comprises:
a first converter bridge electrically coupled to the low voltage side of the step-down transformer;
a second converter bridge electrically coupled to the device ports; and
a power converter transformer having:
a first side electrically coupled to the first converter bridge; and
a second side electrically coupled to the second converter bridge;
wherein at least one of:
at least one of the one or more multiplexers is configured to receive power from at least one of the second converter bridges and deliver power to one or more of the devices; or
the first and second converter bridges of at least one of the power converter modules are configured to bidirectionally manage AC and DC power flows between the device ports, simultaneously.
