Power2EMC – Reduce Emissions in Electric Vehicles through Active Filters and Active Gate Drivers
Power2EMC – empowering Electro-Magnetic-Compliance in vehicles –successfully reduces filters by up to 50% in the DCDC-Converter, the On Board-Charger and the Drive-Inverter.
Within Power2EMC – one project of the NovoMotive project-family – we have tested and elaborated concepts to turn down the electromagnetic noise:
- Active filtering – Active electric-noise cancellation by compensation – with a variety of compensation algorithms
- Gate Driver concepts – efficient and well-adapted drivers for the Power-Semiconductors
- Magnetics reduction concepts to low-volume - ferrite-based - hybrid - filters
It performs on all three components, the DCDC-Converter, the On-Board-Charger, the Drive-Inverter, and as well on the vehicle-like common demonstrator.
The results show: Best concept in the triangle of safety, costs and volume is the Power2EMC hybrid filter approach with active filters, a small passive pre-filter and well-adjusted gate drivers. This brings the electromagnetic noise down to OEM requirements including the following benefits:
- Filter volume in car is reduced by about ~50% ⚡
- Magnetics for filters are reduced by >50% ⚡
- Powers independence of rare earth materials ⚡
- shielded wiring no more needed ⚡
- Cost-reduction on filter-level and system-level ⚡
The project and project-family has been funded by the German Federal Ministry for Economic Affairs and Energy (BMWE) and the EuropeanUnion (NextGenerationEU)
