Can I Build a DC-DC converter, never existed before?

Try PCBWay PCB/CNC/3DP services using the referral link - https://pcbway.com/g/Cnkx4p I’m building a multi-port DC-DC converter that can charge up to four batteries at the same time 🔋 The system is primarily powered by a low-voltage DC grid, but the really cool part is that power can flow bidirectionally — from any port to any other port. This makes it incredibly flexible for energy storage and redistribution. I tested it up to 10 kW peak power, which was… honestly both awesome and slightly terrifying 😅 If you’re into power electronics, high-power DC systems or DIY energy projects, you’ll enjoy this one! ====================================== Dual Active Bridge Converter - https://www.ti.com/lit/ug/tidues0e/ti...
