4 Conclusion

Texas Instruments LM5170-Q1 current controller is used to design buck converter for battery equalizer system. Battery equalizer helps to balance two 12-V batteries in commercial vehicles and allows commercial vehicle manufacturers to utilize both 12-V and 24-V loads more effectively. The presented solution with LM5170-Q1 can achieve well-balanced battery voltages, enhancing the batteries lifespan and overall system performance. The design is straightforward and can easily be modified for different commercial vehicles with different combination of electronics. The closed loop designs are presented, too, which can be followed by the readers in their own designs.
