Automotive meets power electronics and IT – designing an automotive On-Board Charger for electrical vehicles requires the convergence of multiple engineering disciplines, to result in a cost-efficient, reliable and safe product for volume manufacturing. Achieving a high power density and electrical efficiency in a small target package implies a complex optimization task of placing all components and their interconnections, given the constraints of their thermal, electromagnetic and isolation needs and impacts. The control logic is based on a multi-processor system, in order to realize not only the vehicle integration, but also fast digital signal processing for the control algorithms, and IP-based protocol stacks for the communications with the charging infrastructure. An increasing demand for cyber-security provisions is driven by the introduction of smart charging features.
