摘要 |
A power system is disclosed that includes a fuel cell stack primary power source, a secondary power source, a first direct current bus, a first voltage controlled element that electrically couples power from the secondary power source to the first direct current bus when a voltage across the secondary power source is greater than a voltage across the fuel cell stack primary power source, a second voltage controlled element that electrically couples power from the fuel cell stack primary power source to the first direct current bus when the voltage across the fuel cell stack primary power source is greater than the voltage across the secondary power source, and at least one balance of plant load electrically coupled to the first direct current bus.
