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 uses a two-stage approach to convert fuel cell voltage (ranging from 60VDC to 600VDC) to grid voltage (400VAC) with high flexibility, efficiency, and safety. The system includes DC/DC resonant converters, a DC/AC AFE converter, and a control panel, allowing for customization based on fuel cell power levels and voltage ratios. It supports various models (e.g., 8YC30, 8YC100) with different power outputs and specifications. The system ensures galvanic isolation between the fuel cell and the DC-link for safety and control reasons, and it is modular and customizable. The 8YS Fuel Cell is ideal for applications requiring efficient and safe power conversion from fuel cells to the grid.
