RIPPLE CURRENT ELIMINATION CIRCUIT CAPABLE OF EXTENDING THE LIFETIME OF A FUEL BATTERY

摘要

PURPOSE: A ripple current elimination circuit is provided to improve performance of a fuel battery by eliminating a high frequency ripple current and a low frequency ripple current at the same time.;CONSTITUTION: A high frequency ripple current elimination unit(11) has a transformer(111) and a capacitor. A low frequency ripple current elimination unit(12) is included composed of an active filter. The low frequency ripple current elimination unit creates a compensating current. The compensating current has same frequency as a low frequency ripple current and has opposite phase. The low frequency ripple current elimination unit provides the compensating current to a current which is inputted to an input terminal.;COPYRIGHT KIPO 2012
