    This came from my upgraded Lectric Leopard with only 1300 miles that was parted out before its time. It was a result of not having any space in my conversion, which netted me a strong DC-DC converter that takes up very little space. It is nothing more than a cold plate made from two flat .095"...

    This info must be here somewhere, please point me to the old thread... I am using a Leaf battery pack ~400V, and need to buy a DC-DC converter for the 400v-13.9v. I will be using a 12v lead acid battery as it is needed to turn on the contactors. I have put together a list of the cars current...
  3. Batteries and Charging
    Hi, I have a VW campervan converted to electric. 144V traction battery pack connected to the usual 12V aux, converted by someone else but I know how most of it works. Since the weekend, the aux battery hasn't been charging. Normally a relay would connect the circuit when the ignition was...

    Some of the principles I discussed in the "Magnetics" thread were in preparation for the design of the transformer I used for this DC-DC boost converter. For my purposes, I wanted to boost a 24V nominal battery to about 240 VDC to be used with a VFD for a three phase motor. I have built several...
  5. Technical Discussion
    About 2 years ago there was a thread discussing Evnetics possibly developing a DC-DC converter. The project was shelved mostly because I couldn't get the manufactured cost below $200, and then the locomotive drive system project came along and derailed (ahem) all other projects. Well, we...
