EMB1499Q: TIDA-00817: Doubt regarding connection on primary side of the flyback transformer.

https://www.ti.com/lit/ug/tidubz7/tidubz7.pdf#:~:text=The%2016-Cell%20Lithium-Ion%20Battery%20Active%20Balance%20Reference%20Design,applications%20like%20xEV%20vehicles%20and%20energy%20storage%20systems.

Dear Sir,

I wanted to clarify a doubt regarding Figure 1. TIDA-00817 Block Diagram (Page no:3), On the primary side of transformer there is a load connected to the 12/24V battery (seen in fig.). What is the purpose of connecting load here? Is the load always connected (or) optional?
Instead of a battery and load can a single super capacitor be used here.

Thanks and Regards

    Hi Archana,

    The load is representative of any other loads on a 12V or 24V supply such as for the MCU. it is not a necessity for the flyback design.

    Thanks for the clarification, so if I choose to provide supply for my MCU using the battery pack itself, can the 12/24V rechargeable battery be replaced with a supercapacitor?

    Regards

    To explain in detail, I would like to replace the 12/24V battery & load : with a supercapacitor, in this case is it possible to charge the supercapacitor by selecting a high voltage cell and then transferring the energy from super capacitor back into a low voltage cell of the pack (also it is possible to specify a upper limit for magnitude of current during energy transfer process).
    MCU and other required components will be powered using the battery pack.

    Hi Archana,

    Yes, a super capacitor could replace the 12V battery as the purpose of the battery is to be a location to transfer charge from the cells to the battery.
