    The purpose of this project is to design a 760V to 12V DC/DC converter to be used as an integrated auxilliary power supply within various products operating from a nominal 760 VDC source. A possible converter design could be based on off-line power switches but with the main difference that the input voltage is higher than what most off-line switchers on the market can handle. A staged project se...

    Microcontroller for smart charger - preferable PIC16 5 дней(-я) left
    ПОДТВЕРЖДЕН

    The smart charger allows a user to switch the charge process of e-bike lithium batteries off earlier: at 40% (winter storage - degradation is minimal), 60% - 70% - 80% (save lifetime and decrease driving range) and 100%. Switching off takes place based on the voltages that correspond with the 4 "save" positions. As this is not 100% accurate, the switching points are recalculated by mea...
