Inhalt:
This paper presents the concept and the implementation of the DC/DC-Converter of a bidirectional wallbox. The focus is on the application of the quantum control strategy for series resonant converters, while at the same time realizing a sensorless and load-independent soft switching technique. The result is a bidirectional DC/DC converter achieving an efficiency of 99,1% @ 250V and 99,2% @ 500V at 5,7 kW/L.
