    Why am I only getting 26.4w output?

    I am trying to charge my 52v ebike battery to 54.6v.

    I am using 750w 12.1v ac/dc power supply as a source.
    I have output set to 54.6v and 12a.
    LVP is set to 11.5v.
    STR is set to 11.8v.
    OCP is set to 12.0a.
    OVP is set to 54.6v.
    ATO is on.
    MOD is set to NOR.

     

    I tried setting the voltage to 75v but the output remained at 26.4w.  It does not seem to matter what settings I change, it will not go above 26.4w.

    If I change to a 24v or 36v power supply then I can get the 200-300w output that is my goal.

    Is to be expected due to the nature of the boost converter circuit? would it provide more power and less efficiency if the mosfets and capacitors were larger? Can we lower the operating frequency? Would that make a difference?

    The instructions seem to insist there is nothing else that can be done.  The boost converter is regulated by ohms law.

    Hello ,

    Please confirm if it is #200580, https://www.amazon.com/dp/B098SVD2B8?ref=myi_title_dp

    No matter which  converter is,  the higher votlage difference is, the more the power dissipation is . From 12v to 56v, the votlage difference is not low. Since more power has been consumed on conver circuit, the actual output power is not enough. That is why 24v or 36v input voltage can work.

    Best regards.
