Rectifier circuit for e-mobility charging stations allows for two operating modes - efficient switching for use of different, inductive charging systems
inductive charging system (top) and an embodiment of the system according to the invention (bottom), each with an identical transmitter unit (left). Legend: Power source (a), converters (b, c, h), transmitter and receiver coils (e / f), battery (i) and power factor correction units (k). The receiver/rectifier circuit (g) according to the invention also comprises a switch (s) and four diodes (d) [University of Stuttgart].
- High charging efficiency independent of the nominal power of the transmitter unit
- Significant improvement of interoperability
- More consistent utilization of the charging infrastructure
- Switching can be done manually or automatically (via microcontroller)
