Power management utilizing synchronous common coupling

A method of utilizing synchronous common coupling for power management, the method comprising the steps of:

• receiving power from a source through at least one of a plurality of ports, wherein at least one of the plurality of ports is connected to a load;
• and
• controlling, by control circuitry, the power through a plurality of electrically isolated stacks connected through a synchronous common coupling, each electrically isolated stack comprising a plurality of cascaded stages and connected to a source or load through one of the plurality of ports, wherein the synchronous common coupling connects only power between each of the plurality of electrically isolated stacks and is configured to maintain electrical isolation for each of the plurality of stages in the plurality of electrically isolated stacks.
