摘要:
A method and system for balancing output currents of parallel connected first and second DC/DC converters is provided. In operation, the first converter (i) receives, via a communications line connected between the converters such as a CAN bus, a value of the output current of the second converter and (ii) uses this value in weighing an output voltage comparison performed by the first converter for generating the output current of the first converter to thereby adjust the output current of the first converter based on this value. Likewise, the second converter (i) receives, via the communications line, a value of the output current of the first converter and (ii) uses this value in weighing an output voltage comparison performed by the second converter for generating the output current of the second converter to thereby adjust the output current of the second converter based on this value.
