The BDC546 is mainly conceived for fuel cell applications, in which it acts as a link between fuel cell, HV battery and drive. Due to its wide voltage range the BDC546 is primarily designed for use in high-performance drives, such as fuel cell buses. The BDC546 can also be used in test bench applications or in combination with stationary transformers as a powerful DC fast charger.

Generally, the BDC546 can be used anywhere, where very high power must be transferred between different voltage levels. By means of the DC/DC converter, the high-side voltage and the voltage on the fuel cell side can be controlled, and thus the inertia of the fuel cell system can be compensated.

Due to the bidirectionality the fuel cell units can selectively become activated. The system has excellent flexibility so that customers can implement other control functions.
