Design and Development of Multilevel DC/DC Converters

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