摘要：

In this paper, the design guideline for a high-power-density inverter for fuel-cell (FC) applications is presented. Such an inverter can lead to savings in volume and weight due to high-frequency operation. In addition, we present a guideline to determine the optimal size of the input filter. It is also illustrated that, for such a topology, an optimal choice of transformer leakage inductance is necessary to achieve low power loss and to establish a balance between efficiency and reliability. Transient load condition, which may degrade FC-stack reliability, is handled through a battery-sourced energy-buffering unit. Experimental results demonstrating the nominal operations of inverter and energy buffering unit are presented.
