DC/DC-DC/AC structure

Due to the characteristics of fuel cells, power inverters for fuel cells consist of a DC/DC inverting element to invert low voltage & high current DC into constant high voltage DC, and a DC/AC inverting element to invert high-raised voltage DC into constant AC. DC output voltage of fuel cells can fluctuate up to double according to the amount of power, therefore, the DC/DC inverting element controls the output power by inverting input power into constant DC voltage, and the DC/AC inverting element operates in parallel with common power supply for grid connection. When faults in the common power supply occur, the DC/AC inverting part stops grid-connectionand takes it automatically off the grid.

High Efficiency

 

Simple system configuration and efficient spacing successfully reduces the size to easily fit into customer systems while boasting a high efficiency rate.

 

Customization

 

1kW~260kW capacity of inverters for PEMFC, SOFC and MCFC types were already developed for residential, commercial and power plant uses. Customized power inverters contribute to optimal system operations. 

Following options are provided for customization;

 

Air / liquid cooling
RS-485 / CAN open
On / off-grid
Single / parallel structure

 

Complies with grid connection standards such as UL1741 and IEEE1547.
