Hitachi Review

Highlight

Recently, demands for space-saving and easier maintenance have been growing among the equipment features demanded by the power converter market. To meet these demands, Hitachi has developed excellent technology in the form of a modular power conversion unit that supports various types of power converters and uses double-sided cooled power modules that provide outstanding cooling performance. By using doublesided cooled power modules, which have excellent heat dissipation and are smaller than conventional single-sided cooled power modules, the developed unit can house all of the key components needed for power conversion in a 55% smaller volume than conventional units, achieving better maintainability in a more compact size. Hitachi will continue working on global manufacturing, initially with UPSs equipped with this developed unit, and later by incorporating the unit into other power converters.
