About the DAB 3k3W - 3.3 kW Dual Active Bridge power board

DAB 3k3W - 3.3 kW Dual Active Bridge power board is an open source PCB design by ajkumar-1907, published on GitHub under the MIT license. It is a 4-layer board measuring 220 × 150 mm, with 160 components from 31 distinct parts.

Other key parts include the TI UCC21520DW, TI AMC1311BDWV, ST L78L05ACUTR and Diodes AP2112K-3.3TRG1. By type, the board carries 70 capacitors, 47 resistors, 10 diodes, 9 ICs, 8 transistors and 2 connectors.

From the project

Open-source library of power electronics converter topologies — KiCad schematics, working principles, use cases, and design notes for DC-DC, AC-DC, DC-AC, and AC-AC converters. Free to use, modify, and build on.

A 3.3 kW, 400 V ↔ 350 V bidirectional isolated DC-DC power stage for EV battery charging with V2G (vehicle-to-grid) capability. The board has two SiC full bridges connected through an off-board high-frequency transformer and series inductor. Power flows in either direction, set by the phase shift between the two bridges.

The board is split into three isolated domains: - Primary (PGND1, 400 V) - Secondary (PGND2, 350 V) - Control (GND, 3.3/5 V)
