Characteristics of a pulse-link inverter for fuel cells

This paper proposes a novel DC-AC converter topology for fuel cells. This topology provides pulsed voltage to PWM inverter directly. As the results, it will be possible to reduce the size of this component because of no need for smoothing circuit between boost converter and PWM inverter. Furthermore, this topology is expected to achieve ZVS of the PWM switches because pulsed voltage has certainly zero voltage period in the switching period. This paper analyzes the novel topology called Pulse-link inverter. And it is shown the advantage the converter by the experimental results.
