Traction inverters play a crucial role in the electrification of powertrains in electric vehicles. For battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), a high-voltage power inverter is essential to drive the electric motors.
A new state-of-the-art EMI filter for traction, leveraging insulated over-molding technology, offers a 30% size reduction and 25% weight reduction. This compact design is perfect for electric vehicles and EMI-shielding purposes applications.
Our innovative molding technology uses lead frames to replace traditional PCBs, enabling a more compact design while maintaining high performance. This approach allows for significant downsizing of the overall size without compromising functionality.
The advanced molding technology, the use of lead frames in place of PCBs offers enhanced spatial flexibility. Whether horizontal or vertical layouts are required, our solution can be easily adapted to meet various design needs.
Cyntec’s equivalent circuit model, incorporating component and interconnection parasitics, empowers faster, more accurate design evaluations. Key benefits include:
(1) Quick Insertion Loss Evaluation – Speed up the design process by quickly assessing insertion loss.
(2) EMI Noise Simulation – Seamlessly integrate with the system’s circuit model for EMI noise simulations in both frequency and time domains, ensuring optimal performance.
By implementing a symmetrical structure and shortening the grounding path from the capacitor to the screw hole of the grounding pin, we effectively boost overall insertion loss—showcasing Cyntec’s commitment to high performance design.
The boost choke (Reactor) is a key component of the traction inverter in hybrid and plug-in hybrid vehicles, and its performance and size depend on the magnetic materials used. Cyntec develops alloy powder magnetic materials with high saturation, low loss, and low hysteresis, which help reduce the size and weight of the boost choke while improving conversion efficiency. Cyntec’s advanced boost choke leverages multi-physics (including electrical, thermal, mechanical, and noise analysis) CAE capabilities for better reactor performance and robustness.
