A turbine engine may include a modular power electronics distribution system having a plurality of modules connectable to a pluggable interface. The pluggable interface may be configured to receive and distribute power to the plurality of modules. Each module may include at least one fault isolation switch and a coolant system including an inlet and return line, as well as a metering valve. At least one power bus may be configured to provide electrical power to at least one of a load or a source via a functional segment. The functional segment may be operable to supply electrical power to the load in a desired form. The modular power electronics distribution system may include a controller in communication with the plurality of modules, the controller configured to control at least one fault isolation switch and metering valve.
