Design and Development of Multilevel DC/DC converter

In this video, we showcase the design and development of a high-power, silicon-carbide-based multilevel DC/DC converter engineered specifically for onboard battery systems in modern railway traction.
We walk through the complete process—from topology selection and component optimization to PCB design, thermal management, and full 3D system modelling. You’ll see how the DC-link capacitor bank, laminated busbar, gate-driver circuitry, control boards, and power stage come together.
