主权项

1. A motor power simulating system for fuel cell power module evaluation, comprising:
a fuel cell power module; a ripple current generator; and an electronic load device for consuming the power generated by the fuel cell power module, wherein the ripple current generator is connected directly to the fuel cell power module and the electronic load device, and wherein the ripple current generator consists of a switching variable resistor and a capacitor, and the switching variable resistor is connected to a positive terminal of the fuel cell power module such that the switching variable resistor changes its resistance while having a predetermined frequency to adjust the amplitude of a generated ripple current, thus simulating the ripple current normally found during operation of a fuel cell vehicle.
