1. An energy accumulator module (EAM) coupleable electrically in parallel between a power source and a load, the EAM comprising:
a first transmission line and a second transmission line coupleable to a respective power distribution bus coupling the power source to the load to receive a DC voltage therefrom;
a power converter, comprising:
an inductor coupled at a first end to the first transmission line, and at a second end to a node;
a switching stage arranged to define a buck leg and a boost leg, the buck leg and boost leg electrically coupled at the node and electrically in parallel with the inductor, the buck leg further electrically coupled to the second transmission line; and
a capacitor coupled electrically in series between the boost leg and the second transmission line; and
a controller module configured to receive a first signal indicative of a voltage across the capacitor, a second signal indicative of a first current through the inductor, and a third signal indicative of a load current in at least one of the respective power distribution bus, wherein the controller module is communicatively coupled to the switching stage to selectively control an operation thereof based on the first signal, the second signal, and the third signal;
wherein the switching stage is selectively controllable by the controller module to operate in one of a charge mode and a discharge mode,
wherein the controller module is configured to controllably operate the switching stage in the discharge mode when a rate of rise of the load current is greater than a rate of rise of a second current in at least one of the respective power distribution bus, and
wherein the controller module is configured to controllably operate the switching stage in the charge mode when a rate of decrease of the load current is greater than a rate of decrease of the second current.
