50 kW Partial Power Converter for EV Charging

This paper presents the design and assembly of a 50 kW dual active bridge partial power converter. Due to the reduction in the power processed by the converter, the maximum power observed by the converter is set to 4.7 kW. In consequence, the implementation of silicon-based discrete switching devices is enabled, which reduces the final cost and volume. Additionally, this document presents the design and assembly of the rest of the passive components: transformer, capacitors, heatsink… Finally, all the power stage is embedded inside a standardized enclosure: a 19 inch (482.6 mm) 4U front panel rack.
