Add to compare

The 8YS Fuel Cell is a power converter series designed to help fuel cells with low DC output voltage deliver power to the grid. It addresses the challenge of converting fuel cell voltages, typically ranging from 60VDC to 600VDC, to the grid voltage of 400VAC. The system uses a two-stage approach, which includes a DC/AC AFE converter, an intermediate DC line (DC-LINK), and multiple resonant DC/DC converters that exchange energy between the fuel cell input and the DC-LINK. This design allows for high flexibility, efficiency, and safety. The system is modular, customizable, and provides galvanic isolation between the fuel cell and the DC-LINK. An example system includes a 30kW fuel cell power converter using four DC/DC isolated converters (each at 7.5kW) and one DC/AC AFE inverter to boost the fuel cell output from 120VDC to AC grid at 400VAC.
