APPLICATION
The 1500-3000 Watt Bi-directional non-isolated DC-DC converter, BCA Series, provides a complete solution for in-vehicle power distribution with 12 or 24V/48V battery configurations for a variety of applications including micro and mild hybrid automotive systems. The bi-directional DC/DC converter charges a low side (12 or 24V) battery during normal operation (buck mode) and charges or assists the high voltage (48V) battery in emergency situations (boost mode).
The bidirectional DC/DC converter operates more as an ideal current source with variable direction, thus allowing energy transfer between two voltage domains. Voltage feedback maintains the output voltage within the acceptable operating range and eventually allows a custom charging profile for the battery pack. It regulates the average current flowing between the high voltage and low voltage ports in the direction selected via CAN interface.
It is packaged in an unprecedented low profile, mechanically enclosed package. The package makes the unit ideal for harsh shock and vibration requirements as well as easy integration with a battery pack.
