    INFINEON CONTROLLERS FOR DUMMIES

    The shottky is in series at V+(in). So it looks like a protection diode in case of revers polarity. May be a blocking series-shottky at V+(out) should de recommended as well, preventing harmful back current, when the Recom is powered down. Georg

    Infineon transistor modification

    Well done, philf! All your cicuitry run at first go. For those, who forego teeny-weeny-solderings. You can get this DC/DC converters up to 72 Volts input : http://www.recom-international.de/pdf/Innoline-2008/R-78HBxx-0.5_L.pdf. With a small series resistor still higher. Price. 14 Euro ca. 22...

    Infineon transistor modification

    Coming to think of any-voltage: Why not feed the controller with full 48V/72 Volt only for the power circuit and a partial akku voltage of e.g. 24V for electronic control? Two red wires are already at hand. Dissipation loss will be minimal. LVC could be set in 0.1V-steps. (representing whole...

    Infineon has REGEN BRAKING (and more)

    Thanks philf, Yes it is a standard serial port and the level-shifting is done by the SIO-part of this circuit-board: http://www.mikrokopter.de/ucwiki/en/SerCon. 5 Volts are from a DC-powersupply. I did it this way. Now I have tested the procedure with EB806 and EB812. May be it´s the...

    Infineon has REGEN BRAKING (and more)

    Thanks a lot philf, - wow, that was fast. It is me who is slow. Yes it´s an old school connection, used to talk with an Atmega. Now I have tried that and also another option of connecting pins 1,4,6 and 7,8 seperately. (found it here ...

    Infineon has REGEN BRAKING (and more)

    Hallo, can not get a Max232 based RS232/TTL-Converter going to transfer data to the Controller. Followed this instruction: Load PC software, load demo file to send to controller and hit "Transmit'. THEN connect the controller. But no statusbar appeared. How long should I wait? Echo test in...

    Meanwell SP-500-48 as a charger ?

    Hey guys, somebody out there experienced in Meanwell AC/DC SPS like this SP-500-48, http://www.meanwell.com/search/sp-500/default.htm. The SP-Supply should charge a 12s3p akku pack of SONY US26650VT aka Konion2500. Can it be used as a charger as is, or will current limiting cause concern. The...
