Active Precharge PCB

Project Details

  • I designed a buck-converter-style active precharge circuit that has negligible power loss, maintains a constant precharge current, can be multiple times faster than our current passive RC-style pre-charge, and is rated for any system up to 1200V, providing a roughly 2x safety factor for our car's 588V battery.

    An overview of my first-principles approach used to design the circuit is outlined in this proposal document:
