Abstract: A system and method for controlling power converters are disclosed. Briefly described, one embodiment is a method comprising communicating at least one first control signal to an alternating current/direct current (AC/DC) power converter from a multi-converter system controller, the AC/DC power converter and the multi-converter system controller residing in a power system electronics housing, and communicating at least one second control signal to a direct current/direct current (DC/DC) power converter from the multi-converter system controller, the DC/DC power converter residing in a power system electronics housing.

Abstract: A power converter may employ a planar transformer to minimize winding conduction loss, and the switching devices of the power converter may be aligned in lines parallel to an edge of the planar transformer to minimize the termination leakage inductance. The windings of the planar transformer may be thermally conductively coupled to one or more heat sinks carried by a circuit board which are with respective ones of the switching devices, to provide a cooling path for the planar transformer.

Abstract: A self-supporting thermally-protective plant enclosure includes a plurality of elongated hollow closure bodies each having a pair of outer and inner transparent walls. Each outer and inner wall are peripherally interconnected by a base, a top and a pair of opposite sides extending upwardly from the base to the top. Each closure body is closed along the opposite sides and base and is open at least through a portion of the top, defining an internal cavity in the closure body capable of receiving and holding a quantity of fluid therein. The closure bodies are positioned in side-by-side relation and are coupled one closure body to the next along the opposite sides thereof so as to form the plant enclosure with an open top and bottom and an annular configuration surrounding a protective plant growth chamber.
